Hint: If you find Ixxo for a sphere with radius Ro and Ixxi for a sphere with radius Ri, then for a hollow sphere with outer radius Ro and inner radius Ri, Ixx = Ixxo - Ixxi. Similar relationships exist for the other elements of the inertia tensor. This is a fundamental property of definite integrals: integral 0 to b - integral 0 ...
