$L = 32 π$ $L=32pi$

Explanation:

$the angular acceleration of a rotating object is given by:$ $"the angular acceleration of a rotating object is given by: "$
$alpha=(Delta omega)/(Delta t)$
$alpha=(cancel(2)pi(f_f-f_i))/cancel(2)$
$alpha=pi(2-1)$
$alpha=pi$
$"Torque for an object making rotary motion is given as:"$
$L=alpha*I$
$"we can write " m*r^2 " instead I"$
$L=alpha* m*r^2$
$L=pi*2*4^2$
$L=32pi$
