Member advised to use the homework template for posts in the homework sections of PF.

Im new at this Physics forum and i don't quite know anyone here.

I came here because I'm doing a paper about "The Physics of Boomerangs" and so i found a topic about it where you explained a guy how to calculate the moment of inertia on a simple model of a boomerang.

However, I didnt understand the last part, about the end of the calculus. Gneill said I new = I + M.r^2 . So I use that formula 1/12 x M(a^2+b^2) and then add M x r^2 ? And after that you multiply by 3 ? In that case scenario r = 5.4 ?
