Answer:
h = 40 cm
Step-by-step explanation:
The volume (V) of a cylinder is calculated using the formula
V = πr²h ( r is the radius and h the height )
here V = 3240π, thus
π × 9² h = 3240π
81πh = 3240π ( divide both sides by 81π )
h = [tex]\frac{3240\pi }{81\pi }[/tex] = [tex]\frac{3240}{81}[/tex] = 40
