@sarah-khan could u upload question I can't understand weather it's semi ring or disk
@kds-dhanik-samba it's semiring
@kds-dhanik-samba The question is :-
A uniform wire of length l and mass M is bent in the shape of a semicircle of radius r. Calculate moment of inertia about XX'

@sarah-khan it was nothing but mr^2 as mass was at distance r from every point so find r
Is same ring
