A uniform disc having radius \( 2 R \) and mass density \( \sigma \) as shown in figure. If a small disc of radius \( R \) is cut
P
from the disc as shown. Then find out the moment of inertia of remaining disc around the axis that passes
W
through \( O \) and is perpendicular to the plane of the page.
