A closed cylindrical tank contains \(20 \pi\) cubic feet of water and is filled to half its capacity. When the tank is placed upright on its circular base on level ground, the height of the water in the tank is 5 feet. When the tank is placed on its side on level ground, what is the height, in feet, of the surface of the water above the ground?
(A) 1
(B) 1.5
(C) 2
(D) 2.5
(E) 3
(A) 1
(B) 1.5

Since the tank is half filled, when it's placed on the side, the water will occupy the same half meaning, height of water will be the radius of the circular base.
\(20\pi = \pi * r^2 * 5\)
\(r = 2\)
Answer is C) 2

If you lie the tank on its side, the water will spread out to occupy the entire lenght making it 10 why did you still use the lenght as 5?
