Moment of Inertia of Initial disc about center = Moment of inertia about center of part that is removed+ moment of inertia about center of whatever is left

@Raghav Vaidyanathan Now u may see

@Kyle Finch What I said above still applies. The MOI of the whole disc is sum of the removed part and what's left.

@Raghav Vaidyanathan OK thanks , can u also tell me the solution to this \(\frac{dy}{dx}=\frac{x+\sqrt{x^2-4y}}{2}\)
