A flywheel rotating about a fixed axis has a kinetic energy of 360 joules when its angular speed is \( 30 \mathrm{rad} / \mathrm{sec} \). The moment of inertia of the wheel about the axis of rotation is :
(A) \( 0.6 \mathrm{~kg} \times \) metre \( ^{2} \)
(B) \( 0.15 \mathrm{~kg} \times \) metre \( ^{2} \)
(C) \( 0.8 \mathrm{~kg} \times \) metre \( ^{2} \)
(D) \( 0.75 \mathrm{~kg} \times \) metre \( ^{2} \)
