Consider the moment of inertia I of the rigid homogeneous disc of mass M as shown in the figure about an axis through its center (different shadings only differentiate the two parts of the disc each with equal mass M/2 ). Which one of the following statements concerning I is correct?

A uniform rod of mass 2M is bent into four adjacent semicircles each of radius r all lying in the same plane. The moment of inertia of the bent rod about an axis through one end A and perpendicular to plane of rod is.
