Answer:
18 units
Step-by-step explanation:
You have that V = 1/3 * pi * r^2 * h and V = 150 * pi and r = 5, so you substitute those second two values into the first equation.
150pi = 1/3 * pi * 5^2 * h
simplifying the left side,
150pi = 25/3 * pi * h
divide both sides by pi
150 = 25/3 * h
divide both sides by 25/3
h = 18
