This is not homework, just my practise question for an exam.(adsbygoogle = window.adsbygoogle || []).push({});

I keep getting an answer of 3/5MR^2 when the correct one is 2/5MR^2, and that was only because I fluked it by deciding to change my intergrand a little bit.

I've some sources including one from hyperphysics which suggests considering the sphere as a stack of disks. I'm completely stumped. I've used double intergrals before, but in this one the integrands I would have never though of using them - how did they get them?

If someone could please run through me how to solve this sphere I would be grateful. No weird short cuts please...
