Question

Please help me with this

Answer 1

h = 40 cm

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 =
`(3240\pi )/(81\pi )` =
`(3240)/(81)` = 40
