A water tank in the shape of a right circular cylinder has a base radius of 30 meters and a volume of 2700 pi cubic meters. What is the number of meters in the height of the tank?
The formula for a cylinder is V = π*r^2*h
Plug in the numbers we know and we'll get 2700π = π(30)^2*h
Then just solve!
2700π = π(30)^2*h
2700π = 900π*h
2700/900 = 3
2700π = 900π * 3
2700π = 2700π
h = 3 meters
