I had to find the moment of inertia of a sphere of varying density where the density is some constant times the radius.(adsbygoogle = window.adsbygoogle || []).push({});

I used the equations from here

http://hyperphysics.phy-astr.gsu.edu/hbase/isph.html

I inserted this d=cr in for the density.

For the mass I used dm=4(pi)(d)r^2dr, inserted the density, integrated and solved for c.

After substitution I the answer I got was 2/15mr^2.

Does this sound right?
