NOTE: is the mass of the body. All equations use the outer radius of the shell. is the thickness of the shell and is assumed small. :is the density of the body. If , the approximate calculated volume is no more than 10.7% larger than the exact volume. For exact results use the Sphere equations for the outer and inner radii. All of the above results assume that the body has constant density. For none constant density see the general integral forms of Mass, Mass Moment of Inertia, and Mass Radius of Gyration.
