An annular cylinder has an inside radius of r1​ and an outside radius of r2​ (see accompanying figure). Its moment of inertia is I=21​M(r12​+r22​). The two radii are increasing at a rate of 4 centimeters per second. Calculate the rate at which I is changing at the instant the radii are 8 centimeters and 10 centimeters. (Assume mass, M is a constant.) =++ =M +⋅) =M(++⋅⋅ Rate =M cm2/sec
