A satellite launch rocket has a cylindrical fuel tank. The fuel tank can hold V cubic meters of fuel. If the tank measures d meters across, what is the height of the tank in meters?

The volume of a cylinder with flat ends is (pi) x (radius squared) x (length).

Radius of the tank = 1/2 diameter = d/2.

Volume = (pi) x (d/2) ² x (height)

Height = (V) / (pi x d²/4)

Height = (4V) / (pi d²)
