Concepts and Reason
This problem can be solved using two concepts: moment of inertia for the hollow sphere, and conversion of units.
Calculate the mass in kilograms by first dividing the radius of the sphere into its diameter. Substitute the values in the expression for moment of inertia hollow sphere to calculate moment of inertia for the tennis ball around an axis passing through its center.
