Moment of inertia for hollow sphere: 2/3 mr^2 where m is the mass and r is the radius of the sphere.
Solid sphere: 2/5 mr^2
The formulas for moment of inertia for just about any shape you need can be found here (you need to scroll down a little ways): http://scienceworld.wolfram.com/physics/MomentofInertia.html

Hollow sphere: I = 2/3*m*r^2
Solid Sphere: I = 2/5*m*r^2

Moment of Inertia is a mathematical expresion which relates to the inherent energy of a mass structure be it a cube ,sphere or any other irregular shape and the product of a frequency square of the matter wave.As Per Louis De Broglie all matter is osciliatory and can be represented as a wave hence with frequency.
