Why does a solid sphere have a smaller moment of inertia than a hollow cylinder of the same mass and radius, about an axis passing through their axes of symmetry?

Question

Why does a solid sphere have a smaller moment of inertia than a hollow cylinder of the same mass and radius, about an axis passing through their axes of symmetry?, The mass distribution of the solid sphere is more concentrated towards its center compared to the hollow cylinder., The solid sphere has a smaller radius than the hollow cylinder, resulting in a smaller moment of inertia., The material used to make the solid sphere is less dense compared to the material used for the hollow cylinder, affecting the moment of inertia., The solid sphere has a larger mass than the hollow cylinder, contributing to a smaller moment of inertia.
