Perpendicular Axis Theorem
The moment of inertia, for a point-mass M rotating around a circle of radius r, is M times r squared. — Click for http://en.wikipedia.org/wiki/Moment_of_inertia
![$\displaystyle I = \frac{M}{\pi R^2}\cdot 4\int_0^{\pi/2} \int_0^R [r\cos(\theta)]^2\, r\,dr\,d\theta
= \frac{1}{4}MR^2
