Calculate the rotational inertia for one of the following objects, but not both.

a) A cylinder of hight 3m, radius 4m about its central axis. The density varies with radius. Rho = 2 r2 kg/m5.

b) A cone with its top removed about its central axis. It would have been a cone of height 6 meters and radius 2 meters, but the top two meters were chopped off (The part farthest from the base). The density is 2 kg/m3.
