Answer 4

i forget the steps.. this is for summer homework

Answer 5

You have your formula, and \(C = 65\pi\) . Just plug it in to \[A=\pi \left(\frac{65\pi}{2\pi}\right)^2\]

Answer 6

So what is (65)\(^2\)

Answer 7

its 4,225??

Answer 8

Yes, now (2)\(^2\)?

Answer 9

4?

Answer 10

Alright. So you have \[A=\pi \left(\frac{4225\pi^2}{4\pi^2}\right)\]The \(\pi^2\)s can cancel each other out \[A=\pi\cdot \left(\frac{4225 \cancel{\pi^2}}{4\cancel{\pi^2}}\right)\] Now what is 4225/4?

Answer 11

1,056.25?

Answer 12
