    Could somebody please explain why the cylinder has the least moment of intertia about the axis? And which one has the greatest, the ring?

    You have to do the integral to find that out, or look up their values online. Do you know what MOI means?

    Big hint: The moment of inertia is the description of how mass is distributed about an axis.
