A disk with uniform density and radius 0.467 m used to weigh 33.74 kg, but then a hole was punched out. The black arrow in the image above shows the axis of rotation. "he hole has radius 0.0572 m, and has its center 0.171 m away from the center of the disk. What is the moment of inertia of the disk with a hole? Hint: only a scientist could call a hole negative mass! Find the mass taken away based on hole size and disk)
