## Homework Statement

Hi there.

Im trying to find the moment of inertia for a 2/3 empty cylinder, could anyone see if I solved this correctly?

Someone told me it's wrong, but I don't know why exactly, so any thoughts would be much appreciated.

(I added the question and the attempt to solve it in a picture)The answer I got is 13/18 * M * r0^2.

Does it make sense that its more than the moment of inertia of a full cylinder? (1/2 * M r0^2)
