Show that the moment of inertia of a sphere of radius R R of total mass M

Show that the moment of inertia of a sphere of radius $R$ of total mass $M$ with uniform mass density about any axis passing through the center of the sphere is $\frac{2}{5}M{R}^2$. Note that the mass density of the sphere is $\delta =M/\left(\frac{4}{3}\pi R^3\right)$.
