A circular disc of plywood has a mass of 4kg and a radius R=0.5m. A circular hole of radius R/2 is cut out from the disc. The center of the hole is located at a distance R/2 from the center of the disc. Determine the Moment of Inertia of the remaining portion about an axis passing through the center of the original disc and perpendicular its plane. Also find the moment of Inertia about its Center of Mass.
