Answer:

\boxed{Height \: of \: cylinder = 9 \: centimeters}

Given:

Volume of cylinder = 576π cubic centimeters

Radius of cylinder (r) = 8 centimeters

Step-by-step explanation:

Let the height of cylinder be 'h'

=  > Volume \:  of  \: cylinder  = \pi {r}^{2} h \\  \\  =  > 576 \cancel{\pi} = \cancel{ \pi}( {8}^{2} )h \\  \\  =  > 576 = 64h \\  \\  =  > 64h = 576 \\  \\  =  > h =  \frac{576}{64}  \\  \\  =  > h = 9 \: centimeters

Height of cylinder = 9 centimeters
