I've been doing calculus for too long, and am completely blanking on how to do this question. I know you have to use $ r^2 = x^2 + y^2$ but I'm pretty sure I'm doing it wrong.

You are already there...$r^2 = 14 \implies x^2+y^2 = 14$. This is a circle centered at the origin and have a radius of $\sqrt{14}$.
