I need to calculate the radius of gyration for a generic, convex polygon, where the density is constant, the axis of rotation is the centroid (which is known), and the positions of the vertices are known. Does such an equation exist?

I would triangulate the two polygon parts separated by the axis individually. And then workout the inertial moment around that axis.
