Answer to Yahoo! question

Hey!
        Here's the answer:

Area = PI * (radius ^ 2) = 169 *  PI (given).
Therefore, radius ^ 2 = 169
Therefore, taking the square root, radius = 13
Circumference = 2 * PI * radius = 2 * PI * 13 = 26 * PI = 81.6814089933


Hope it helps. Let me know if you have any more questions!

Have a great and blessed day!

Good luck,
