The tаble shоws the mаsses аnd the cооrdinates x and y of a set of three point masses in the x-y plane. The masses are interconnected by light struts, forming a rigid body. Calculate the moment of inertia of the rigid body, through the center of mass and perpendicular to the x-y plane. (You must show your full solution steps here. The Scratch Paper is not a substitute for the solution steps.)
