Question: A quantity important in analyzing the rotation of an object is its moment of inertia I. For a ball bearing, the moment of inertia varies

A quantity important in analyzing the rotation of an object is its moment of inertia I. For a ball bearing, the moment of inertia varies directly as its mass m and the square of its radius r. Find the general expression for I if I = 39.9 g · cm² for m = 63.8 g and r = 1.25 cm.
