The height of the cylinder is 6 cm.
If the volume of the cylinder is 54π cm³, and we know the radius, we can use the formula for the volume of a cylinder to figure out the length of the height.
V = πr²h
Substitute
54π = 9hπ
Divide each side by π
54 = 9h
Get h by itself
h = 6, which means that the height of the cylinder is 6 cm.
