$P = 768 π k g \cdot m^{2} \cdot s^{- 1}$ $P=768pi" "kg*m^2*s^-1$

Explanation:

$P = I \cdot ω$ $P=I*omega$
$I = m \cdot r^{2} Moment of inertia$ $I=m*r^2 " Moment of inertia"$
$ω = 2 \cdot π \cdot f$ $omega=2*pi*f$
$P = m \cdot r^{2} \cdot 2 \cdot π \cdot f$ $P=m*r^2*2*pi*f$
$P = 2 \cdot 4^{2} \cdot 2 \cdot π \cdot 12$ $P=2*4^2*2*pi*12$
$P = 4 \cdot 16 \cdot 12 \cdot π P = 64 \cdot 12 \cdot π$ $P=4*16*12*pi" "P=64*12*pi$
$P = 768 π k g \cdot m^{2} \cdot s^{- 1}$ $P=768pi" "kg*m^2*s^-1$
