    Well, the moment of inertia of a hoop is M*R^2. So the moment of inertia of any portion of a hoop is also M*R^2 where M is the mass of that portion. Why are you making up problems, aren't there enough already? :)

    But this hoop is not the same axis.

    haha, I'm crazy, sorry.

    Ok. My confusion suggests a picture might be nice. Everything else seems ok.
