Answer:

#L=192*pi#

Explanation:

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