### Possible Answer

Now imagine this hollow sphere (with no wall ... the radius of gyration of a body about an axis of rotation is defined as the radial distance of a point from the axis of rotation at which,if the whole mass of the body is assumed to be concentrated,its moment of inertia about the given ... - read more

Also, a point mass (m) at the end of a rod of length r has this same moment of inertia and the value r is called the radius of gyration. ... A hollow sphere can be taken to be made up of two stacks of infinitesimally thin, circular hoops, ... - read more
