From a circular ring of mass M M and radius R, R, an arc corresponding to a 90∘ 90^\circ sector is removed. The moment of inertia of the remaining part of the ring about an axis passing through the center of the ring and perpendicular to the plane of the ring is K K times MR2. MR^2. Then the value of K K is:
