I'm having a difficulty in proving the moment of inertia of a sphere.(adsbygoogle = window.adsbygoogle || []).push({});

Using I=p(x^2)dv, we have to show that

I = (3m/r^3) * the integral (from 0 to r) of (x^3)((r^2) - (x^2))^(1/2) dx

where r=radius, x=the axis

I've been trying to prove it and yet no success. if anyone can show me how to do it, i'd greatly appreciate that.

thanks a lot
