**Homework Statement:**Derive the formula for moment of inertia of a hollow sphere.

**Homework Equations:**Required answer ##\frac{2MR^2}{3}##

Consider a Hollow sphere.

At an angle ##Θ## with the vertical, consider a circular ring whose moment of inertia is given by ##MR^2##.

The most basic question I have is, should we consider the volume of the small ring or the area?

After this let us have further discussion.
