$L = - 540 π$ $L=-540pi$

Explanation:

$α = \frac{L}{I}$ $alpha=L/I$
$α : angular acceleration$ $alpha": angular acceleration"$
$L:torque$ $"L:torque"$
$I:moment of inertia$ $"I:moment of inertia"$
$alpha=(omega_2-omega_1)/ (Delta t)$
$alpha=(2 pi*3-2 pi*5)/5$
$alpha=-(4pi)/5$
$I=m*r^2$
$I=3*15^2$
$I=3*225=675$
$L=alpha*I$
$L=-4pi/5*675$
$L=-540pi$
