there is a similar case here :https://www.physicsforums.com/showthread.php?t=296966
so I've tried it and what i did was to equate both individual moment of inertia about z axis (and later applied parallel axis theorm) with negative mass for hole. added both these and found out Ix = M/4 [(1/2)-(r^4/R^2)]
so I think this is wrong, why isn't terms that shows how much distant the hole is located present in the equation? how can we do it. please help.
