Moment of Inertia: Sphere

The moment of inertia of a sphere about its central axis and a thin spherical shell are shown.

For mass M = kg
and radius R = cm
the moment of inertia of a solid sphere is
I(solid sphere) = kg m^2
and the moment of inertia of a thin spherical shell is
I(spherical shell) = kg m^2
