**2. The attempt at a solution**

I found the Moment of Inertia (I) of a disc about the axis passing through the center, perpendicular to the plane and divided by 4. It gave the wrong answer.

So, plz tell me that why dividing by 4 is giving me the wrong answer for the quarter disc.

Also, a hint of how should I start the problem.
