get price### How to Find Moment of Inertia of Solid Sphere

The solid sphere should be sliced to infinitesimally thin solid cylinders. The moment of inertia of a solid cylinder is given as. I = (½)MR 2. For infinitesimally small cylinder moment of inertia can be written as. dI = (½)r 2 dm. dm = ρ dV, where ρ is the density of the solid cylinder and dV is the volume. dV = πr 2 dx.
