I just have no clue why I'm not getting the correct answer on this problem.

Here are my steps

I know that since Momentum is convserved L0 = Lf or I0W0 IfWf

W = angular velocity

so I set (0.12 kg m ^2)(.094 rad/s) = (If)(Wf)

Since we were to treat the Inertia of it to be a hoop the equation of Inertia is I = MR ^2

So this is my final equation (0.12 kg m ^2)(.094 rad/s) = (If)(Wf)

I think where I'm going wrong is when I solved for Inertia (I) for If I used (.36 kg)(.48 ^2)

Please point out what I need to do to correct this problem

Thanks
