having some major derp problems. I can't seem to remember how to find moment of inertia about the COM of and object or even finding the COM for that matter.

I need it to solve a Euler Lagrange problem

Can someone give me an idea on the integrals to use and in what coordinate system?

2. Relevant equations

3. The attempt at a solution

looked at this site, but i'm not sure http://www.efunda.com/math/areas/circlehalf.cfm" [Broken]
