What is the rotational inertia of top 8 meters of a sphere with a radius of 14 meters and a constant density of 64 kg per cubic meter about a vertical axis through the center of the object. This object is like a hemisphere but even more of the bottom is removed. Please answer in kg m².

A uniform spherical shell of mass M-13.0 kg and radius R = 0.970 m can rotate about a vertical axis on frictionless bearings (see the figure). A massless cord passes around the equator of the shell, over a pulley of rotational inertia /-0.110 kg-m² and radius r = 0.140 m, and is attached to a small object of mass m 3.70 kg. There is no friction on the pulley's axle; the cord does not slip on the pulley. What is the speed of the object when it has fallen a distance 1.11 m after being released from rest? Use energy considerations. Number Units m/s M, R C Ne Ur Qu Nu
