If you know the diameter of a circle,
how do you find the following. Explain
the steps clearly
a. the area of that circle?
b. the circumference of the circle?
Step-by-step explanation:
a. Area of a circle = πr², where r means radius.
Step 1: converted diameter to radius.
diameter = 2 radius
In other way of writing, radius = [tex]\frac{1}{2}[/tex] diameter.
Step 2: substitute radius into the formula.
Area of a circle = π([tex]\frac{1}{2}[/tex]d)²
Step 3: substitute π into the formula.
some question is given the value of π), if not substitute 3.14 for π.
Area of a circle = 3.14([tex]\frac{1}{2}[/tex]d)²
Step 4: substitute d into the formula, then we can solve its area.
b. a. Circumference of a circle = 2πr, where r means radius.
Step 1: converted diameter to radius.
diameter = 2 radius
In other way of writing, radius = [tex]\frac{1}{2}[/tex] diameter.
Step 2: substitute radius into the formula.
C = 2π([tex]\frac{1}{2}[/tex]d)
Step 3: substitute π into the formula.
some question is given the value of π), if not substitute 3.14 for π.
C = 2(3.14)([tex]\frac{1}{2}[/tex]d)
Step 4: substitute d into the formula, then we can solve its circumference.

Answer/Explanation:
The formula for a rectangular prism is Length x Width x Height
With this information we can multiply 6x8x2 and get 96 ft³.
This is the volume of the original prism.
Doubling the dimensions means multiplying each side by 2.
The new dimensions would be a.16 b.4 c.12
Use the formula to find volume. 12x16x4=768
The volume of the enlarged prism is 768 feet³
For bonus question, divide 768 by 96.
The scale factor is 8.
Evaluate the expression. Write your answer in scientific notation.

In creating a new scale for the mercury thermometer, Anders Celsius initially set the boiling point of water at _____. A. 0° b. 32° c. 100° d. 273°.
The thermometer is a device that is used to measure the temperature gradient. Anders needs to set the boiling point of water at 100° C.
What is a thermometer?
The thermometer is a device that is used to measure the temperature gradient or the temperature of a body/object.
The boiling point of water is 100°C, therefore, Anders needs to set the boiling point of water at 100° C.
Thus, Anders needs to set the boiling point of water at 100° C.

What measures are taken to discourage car owners, who must wait for the passengers, to use the drop and go parking
Answer:
Short-term parking is generally used by drivers who will be in the airport for less than four hours. On-site long-term parking allows travelers to park their cars for the duration of their trip. Off-site long-term parking offers discounted parking space for travelers wishing to park for the duration of their trip.

False

The exponent signifies repeated multiplication, so will reflect the fact that 1/10 is a factor 3 times.
(1/10)(1/10)(1/10) = (1/10)^3 . . . not (-10)^3
The given equation is FALSE.

Gabrielle is saving money for a vacation. Each week she save $40. Let a represent the total amount of money Gabrielle saves, and let w represent the number of weeks. How much money would she save from 1 to 7 weeks?
Step-by-step explanation:
A = 40w
To Calculate how much she would get in 7 weeks
Substitute w = 7 into A = 40w
⇒ A = 40(7)
⇒ A = 280
Gabrielle would save $280 in 7 weeks

we get to know In quadrilateral left angle is 90°
How ?
{
proof :
As three angles are given 90° So third angle will also be 90°
Reason:
→ Sum of interior angles = 2 (no. of angles - 2 × 180°
→Sum of interior angles = (4-2 × 180°)
→Sum of interior angles = (2 × 180°)
→Sum of interior angles = 360°
}
✿Now let the left angle be x
90° +90° + 90° + x = 360° 180° + 90° + x = 360°270° + x = 360x = 360° - 270°x = 90°we know :

What is the constant term in the expression 8xy − 9x2 y − 5x 6
Answer:
6
Step-by-step explanation:
A constant is a term without a variable.
Every other number has a variable (x,y) to it except for 6.
Feel free to save this for whenever you get stuck on things like this! I know this section is hard.
In the expression 8xy − 9x^2+ y − 5x +6 the constant term is 6 which is a fixed quantity or cannot be changed.
What is polynomial?Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
We have an expression:
[tex]\rm 8xy-9x^2+y-5x+6[/tex]
Let's denote it with f(x,y)
[tex]\rm f(x,y) =8xy-9x^2+y-5x+6[/tex]
As we know the constant term means which cannot be changed that values are fixed or fixed quantity.
From the above expression, the constant value in the expression is 6
Thus, in the expression 8xy − 9x^2+ y − 5x +6 the constant term is 6 which is a fixed quantity or cannot be changed.
