**Problem Statement:**How do you calculate the rotational inertia of a hollow sphere in cartesian (x,y) coordinates?

**Relevant Equations:**I=Mr^2

My physics teacher said its his goal to figure this out before he dies. He has personally solved all objects inertias in cartesian coordinates but cant figure out a hollow sphere's. He said if anyone in the class can help he'd forever be in debt to them and I just genuinely want to help. Do any of you know how to do this?
