A satellite launch rocket has a cylindrical fuel tank. The fuel tank can hold V cubic meters of fuel.

Question

If the tank measures d meters across, what is the height of the tank in meters?

A. 

B. 

C. 

D. 

E. 

Answer 1

The formula for the volume of a cylinder is:

V= pi* D²/4 *H

With:

D= diameter of the cylinder

H= height of the cylinder

If we rearrange the terms of the equation and solve for H, we arrive to the following conclusion:

H= (4*V) / (pi*D²)

This corresponds with answer choice D.
