First off we have to square the radius thats just a fancy way of saying multiply by itself so 2.8 x 2.8 = 7.84 Now we just multiply that by pi!
so 3.14 x 7.84 = 24.6176 now sense we have to round it our final answer would be 24.6
Pii * radius*radius (note: * this start symbol means multiply if you don’t know)
All we have to do is substitute in the values.
Steps:
1. 3.14 * 2.8 * 2.8
2. Answer: 24.617
3. Now we have to round them to the nearest tenth.
So the answer rounded will be: 24.62 yd (squared)
Hope this helps you!!

Valentina made costume crowns for the king and the prince in her school play. She used 5 red gems and 8 purple gems for the king's crown. The prince's crown was smaller, so Valentina only used 4 red gems and 5 purple gems for that one. Which crown had a greater ratio of red gems to purple gems?
Answers
Answer:
The prince's crown had a greater ratio of red gems to purple gems.
Step-by-step explanation:
KING = 5 red / 8 purple
PRINCE = 4 red / 5 purple
Times the ratio for the king by 5
5(5) / 8(5) = 25/40
Times the ratio for the prince by 8
4(8) / 5(8) = 32/40
The prince has a greater ratio of red gems
Hope this is right, and sorry if it is incorrect. Have a good day!

Find the range number of minutes.
Answers
Answer:
Range: 55
Step-by-step explanation:
Range = subtraction of the smallest number in the data set to the greatest number in the data set.
Greatest number: 1 hr (60 minutes)
Smallest number: 5 minutes
Range = 60 - 5
= 55
Hope this helps!
The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6. It is that simple!
Liam is setting up folding chairs for a meeting. If he arranges the chairs in 4 rows of the same length, he
has 7 chairs left over. If he arranges the chairs in 2 rows of that same length, he has 23 left over. How many
chairs does Liam have?
Liam has
chairs.
Answers
Answer:
Liam has 39 chairs.
Step-by-step explanation:
First you have to set up the equation -
4x + 7 = 2x + 23
then isolate the variables
4x - 2x + 7 - 7 = 2x - 2x + 23 - 7
2x = 16
x = 8
then substitute the variable with 8
4(8) + 7 = 39
2(8) + 23 = 39
Liam has 39 chairs.
Enter the expression using exponents.

You are using the equation 4(p – 7) = 44 to determine how many pictures can be saved at one time to the photo stream on your cell phone. Describe the operations in the order that you will perform them to solve the equation. (3 points)
Answers
Step-by-step explanation:
I know that 44÷4=11. So that means P must be 11. But since it's subtracted by 7 we must solve 11+7. Which is 18. So P=18.
4*p= 4p
4*-7=-28
4p—28=44
4p=44+28=72
4p=72
P=72/4
P=18

Kai pen for Ruth’s dog is 7 feet long and 6/1.3 feet wide. Her friend Ralph’s dog pen is 14 feet long and 6/1.2 feet wide. How many times larger is the area of Ralph’s dog pen?
Answers
Answer:
The area of Ralph's dog pen is 2.05 times larger than the area of Ruth's dog pen.
Step-by-step explanation:
Given that the dog pen for Ruth's dog is 7 feet long and 6 / 1.3 feet wide, while her friend Ralph's dog pen is 14 feet long and 6 / 1.2 feet wide, to determine how many times larger is the area of Ralph's dog pen, the following calculation must be performed:
1/3 = 0.333
1/2 = 0.5
7 x 6.333 = X
44,333 = X
14 x 6.5 = X
91 = X
44,333 = 100
91 = X
91 x 100 / 44.333 = X
9,100 / 44,333 = X
205.26 = X
100 = 1
205.26 = X
205.26 / 100 = X
2.05 = X
Thus, the area of Ralph's dog pen is 2.05 times larger than the area of Ruth's dog pen.
