(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I eventually have to solve for maximum angular acceleration of the loop in a magnetic field, and I have gotten everything with the exception of the moment of inertia, so I won't include the emf and B known variables.

Known: a copper wire with a density of [itex]\rho[/itex] = 8960 kg/m^{3}is formed into a circular loop of radius 0.50 m. Cross sectional area of the wire is 1.00 x 10^{-5}m^{2}.

2. Relevant equations

I=MR^{2}

(and eventually) [itex]\tau[/itex] = [itex]\alpha[/itex]I

3. The attempt at a solution

I know since mass isn't given, I need to integrate something so I can use the density. However, it's been a really long time since I've integrated, so I'm not very familar with it. I've been unable to find an equation to find the volume of the 'loop,' so I know integration is the only way.
