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

    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?
