The right circular cone in Figure P9–46 has a mass of 90 kg. Determine the mass moment of inertia about the x-axis.

A flywheel can be considered as being composed of a thin disc and a rim. The rim weighs 322 lb and has diameters of 24 in. and 30 in. The disc weighs 64.4 lb. Determine the mass moment of inertia about the centroidal axis about which the flywheel rotates.
