Find the moment of inertia of a hoop (a thin-walled, hollow ring) with mass M and radius R about an axis perpendicular to the hoop's plane at an edge.(adsbygoogle = window.adsbygoogle || []).push({});

I know that I=n*m*r^2

where n is the inertial constant

but i think my main problem with this is where the axis of rotation is, im thinking that it is through the center of the ring but cant be sure any help would be great.
