The formula for the volume of a right cone is V = (1/3)πr^2h, where r is the radius and h is the height.
We are given that V = 252π/3 and h = 21. Substituting these values in the formula, we get:
252π/3 = (1/3)πr^2(21)
Canceling the 3's and π on both sides, we get:
84 = 7r^2
Dividing both sides by 7, we get:
r^2 = 12
Taking the square root of both sides, we get:
r = √12 = 2√3
Therefore, the radius of the cone is 2√3 units.
Geography is the study of areal differentiation." Discuss with examples
Answer:
Explanation:
Geography is the study of areal differentiation, which refers to the examination of differences and variations between various regions or areas. This involves analyzing the physical, biological, and human factors that contribute to the uniqueness of a place or region.
Physical geography is one of the branches of geography that examines the natural environment, including landforms, climate, vegetation, and water bodies. For example, the Great Rift Valley in Africa is a unique physical feature that has been shaped by tectonic and volcanic activity, resulting in a distinctive landscape with steep cliffs, deep gorges, and flat plains.
Human geography, on the other hand, focuses on the social and cultural aspects of human life, including population, economics, politics, and religion. For example, the cultural differences between different regions in the world can be seen in their language, customs, and beliefs. The Middle East, for instance, is characterized by a strong religious tradition and a long history of conflict, while Southeast Asia is known for its diverse ethnic groups and unique cultural practices.
Geographers also study the interactions between human and natural systems, such as how human activities affect the environment and how the environment influences human activities. For example, the Amazon rainforest in South America is not only a unique natural environment with rich biodiversity, but it is also home to indigenous peoples who have developed sustainable ways of life that are closely linked to the ecosystem.
Overall, the study of areal differentiation in geography provides insight into the complex interactions between physical and human systems and helps us better understand the diversity and uniqueness of different regions around the world.

Which turning point reflected on this map took place in 1453
Answer:
The Ottoman Empire conquered Constantinople and renamed it, Istanbul.
Explanation:
how this helped
Answer:
The turning point reflected in the map that took place in 1453 is option (2) - The Ottoman Empire conquered Constantinople.
Explanation:
This was a significant event in world history because it marked the end of the Byzantine Empire, which had lasted for over a thousand years. The Ottoman Empire, under the leadership of Sultan Mehmed II, captured the city after a long siege and renamed it Istanbul, making it the new capital of the Ottoman Empire. The fall of Constantinople had a major impact on the balance of power in Europe and the Middle East and was seen as a symbolic victory for the Islamic world.
how to prevent drought that lead to loss of profit in agriculture
Answer:
A variety of management practices that increase soil organic matter while reducing soil-moisture loss—such as no-till or reduced tillage, use of cover crops, and conservation crop rotations—may help farms adapt to drought risk.
You have explored some informative examples of models. Now it's time to get creative and make your own model. Here is the requirement checklist for your model:
Model types can include drawings, diagrams, physical models, virtual simulations, or videos.
Model must be created by you, not something selected from an online or outside source.
Submit a presentation, picture, video, or screenshot of your model.
Submit a one-paragraph summary describing the topic you chose, your model, what it represents, how you made it, and the specific science involved. It is important that you are using science terminology and are accurate.
Now that you know how to create and submit your model, you will need to choose a topic for your model. Choose one of the three topics listed below. Select each topic for an overview.
Topic One—Photosynthesis
Topic Two—Cellular Respiration
Topic Three—The Carbon Cycle
Answer:
Sorry, I am unable to provide a drawing so instead, I will provide a summary of each topic. Hope this helps.
Explanation:
Topic One—Photosynthesis:
Photosynthesis is one of the most important processes on Earth, and my model represents the various components that play a role in this process. I created a 3D model of a chloroplast, which is a cellular organelle that is responsible for photosynthesis in plants. The model includes the thylakoid membranes, which are the site of the light-dependent reactions, and the stroma, which is the site of the light-independent reactions. I made the model using a combination of cardboard and clay, and it took me a few hours to complete. This model represents the complex process of photosynthesis and how plants use light energy to create their own food.
Topic Two—Cellular Respiration:
Cellular respiration is the process by which cells convert glucose into energy, and my model represents the various stages involved in this process. I created a diagram that shows the three main stages of cellular respiration: glycolysis, the Krebs cycle, and the electron transport chain. The diagram includes labels for the various molecules involved, such as glucose, ATP, and NADH. I made the diagram using digital software, and it took me a few hours to complete. This model represents the complex process of cellular respiration and how cells convert energy for use in the body.
Topic Three—The Carbon Cycle:
The carbon cycle is the process by which carbon is cycled through the Earth's atmosphere, oceans, and land, and my model represents the various components of this process. I created a physical model that shows the various reservoirs of carbon, including the atmosphere, the ocean, and the biosphere. The model includes arrows that represent the movement of carbon between these reservoirs, such as the uptake of carbon by plants through photosynthesis and the release of carbon by animals through respiration. I made the model using a combination of cardboard and paper, and it took me a few hours to complete. This model represents the complex process of the carbon cycle and how carbon is cycled through the Earth's systems.

What is Afracentricity mean
Afracentricity is a term used to describe a cultural, intellectual, and political movement that centers the experiences, perspectives, and voices of people of African descent.
When did Afracentricity emerge ?Afracentricity emerged in the 1960s and 1970s as a response to the marginalization and oppression of black people in the United States and around the world. The term was coined by Molefi Kete Asante, a scholar of African American studies, who sought to create a framework for understanding the experiences and contributions of African people to world civilization.
At its core, Afracentricity is based on the idea that the experiences and perspectives of black people are central to understanding the world and its history.

What are three ways Lake Tahoe benefits the environment?
Here are three ways that Lake Tahoe benefits the environment:
1. Water filtration: Lake Tahoe is known for its crystal-clear waters, which are the result of the lake's natural filtration system. The water in Lake Tahoe is naturally filtered by surrounding soils and vegetation, which helps to remove pollutants and other harmful substances that could negatively impact water quality.
2. Biodiversity: Lake Tahoe is home to a wide array of plant and animal species. These species help to promote biodiversity and ensure that the lake's ecosystem remains healthy and stable. Additionally, the lake's high elevation and mountainous surroundings make it an important habitat for many rare and endangered species.
3. Recreational opportunities: Lake Tahoe is an important destination for outdoor enthusiasts, including hikers, skiers, and boaters. By providing opportunities for people to enjoy outdoor activities, Lake Tahoe helps to promote an appreciation for nature and the environment. This appreciation can lead to increased awareness of environmental issues and a desire to protect natural resources
Answer:
1. It is home to winter sports, summer outdoor recreation, and scenery enjoyed throughout the year.
2. The Lake Tahoe Basin is home to more than 290 bird, animal and fish species and more than a thousand different plant species.
3. Much of the remaining precipitation drains through marshes and meadows, which are an effective filtration system that remove fine particles before water enters the Lake.
