Final Exam Last Minute Question

I cant remember which it was, so in the case of a ring and a circle of the same mass rolling down an incline, which will gain a greater velocity first and why? I believe it is the circle due to a smaller I, but I am not sure.

A homogeneous disk has a smaller mass moment of inertia than a homogeneous ring of the same outer radius and mass. As a result, less kinetic energy goes into rotation for the disk. Therefore, it will be traveling at a faster rate than the ring.
