Consider a small sphere with a radius of R=1 cm and mass of m=50 g, attached to one end of a nearly massless rod of length r=3 m. 

If someone rotates the rod and sphere using the free end of the rod (the end without the sphere attached) as the axis of rotation, what is the moment of inertia of the combined rod and sphere?
