The area of a circle is:

"r" being the radius and π being 3.14
14. The diameter is 12. So, to get the radius, we would need to halve it. So, the radius would be 6.
Now we plug in 6 for r and 3.14 for π which makes it

which equals 113.04
15. The diameter is 9, so to get the radius we need to halve it to get 4.5
Plug in 4.5 for r and 3.14 for π and we get

which equals 63.585
16. The diameter is 18, so to get the radius we need to halve it to get 9
Plug in 9 for r and 3.14 for π and we get

which equals 254.34
17. The diameter is 8, so to get the radius we need to halve it to get 4.
Plug in 4 for r and 3.14 for π and we get
Answer:C
Step-by-step explanation:
Nancy has 54 pieces of paper, and is going to split them all between her and 5 friends. How many pieces of paper will each person receive?
Answer:
The evaluation of the equation 3 .912+s=5.313 yields; s = 1.401
Evaluation of one variable equation
According to the questions;
We are required to evaluate the equation; 3 .912+s=5.313
Hence, we must subtract 3.912 from both sides of the equation as follows;3 .912+s -3.912 = 5.313 - 3.912.s = 1.401
