A circular disc of mass M and radius R is suspended from a nail in the wall. The nail is fixed very near to the rim of the disc. The moment of inertia of the disc about an axis along the nail is

A circular disc is of mass M and radius r. From it a circualr piece is cut out with a radius of the disc as its diameter. Find the moment of inertia of the remainder about the axix of the disc

From a circular disc of radius R and mass 9 M , a small disc of radius R/3 is removed from the disc. The moment of inertia of the remaining disc about an axis perpendicular to the plane of the disc and passing through O is

The moment of inertia of a circular disc of mass M and radius R about an axis passing thrugh the center of mass is I_(0) . The moment of inertia of another circular disc of same mass and thickness but half the density about the same axis is

From a circular disc of radius R and mass 9M, a small disc of radius R/3 is removed as shown in figure. The moment of inertia of the remaining disc about an axis perpendicular to the plane of the disc and passing through O is
