I explained to you how to solve it. I'm not solving it for you. http://openstudy.com/study#/updates/55ef77fee4b0bf851f6efcc5

solving it would be great :))

4. anonymous

i forget the steps.. this is for summer homework

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

6. anonymous

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

7. anonymous

its 4,225??

8. anonymous

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

9. anonymous

4?

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?

1,056.25?

12. anonymous

are you saying to divide ?

13. anonymous

yes, what is 4225 divided by 4?

14. anonymous

1,056.25

15. anonymous

OOOOOOO
