From a circular disc of radius \( R \) and mass \( 9 \mathrm{M} \), a small disc of radius \( \frac{R}{3} \) is removed as shown in figure. The
\( \mathrm{P} \)
moment of inertia of the remaining disc about an axis perpendicular to the plane of the disc and passing through \( O \) is
(1) \( 4 M R^{2} \)
(2) \( \frac{40}{9} M R^{2} \)
(3) \( 40 M R^{2} \)
(4) \( \frac{37}{9} M R^{2} \)
