$L = 192 \cdot π$ $L=192*pi$

Explanation:

$L :Angular momentum$ $L" :Angular momentum"$
$ω :Angular velocity$ $omega " :Angular velocity"$
$I :moment of inertia of rod$ $I" :moment of inertia of rod"$
$Angular momentum for a rotating object is given by: L= I \cdot ω$ $"Angular momentum for a rotating object is given by: L="I*omega$
$ω = 2 \cdot π \cdot f$ $omega =2*pi*f$
$I = \frac{1}{12} \cdot m \cdot l^{2} (for rod rotating around its center)$ $I=1/12*m*l^2" (for rod rotating around its center)"$
$L = \frac{1}{12} \cdot m \cdot l^{2} \cdot 2 \cdot π \cdot f$ $L=1/12*m*l^2*2*pi*f$
$L = \frac{1}{12} \cdot 8 \cdot 4^{2} \cdot 2 \cdot π \cdot 9$ $L=1/12*8*4^2*2*pi*9$
$L = 192 \cdot π$ $L=192*pi$
