I'm trying to calculate the moment of inertia of a sphere. When I calculate moment of inertia by using dI of a small disk (dI=1/2dmy^2) I have a different answer with when I calculate it through expression I=integral(r^2dm). I have two different answers. Why integral method (the second picture) doesn't work ?
