Acylindrical tank has a radius of 15 ft. and a height of 45 ft. how many cubic feet of water can the tank hold?

To calculate the amount of water the cylindrical tank can hold the volume of cylindrical tank needs to be calculated. The volume of cylindrical tank can be calculated with the following formula:
Volume = π x (radius of cylinder) x (radius of cylinder) x (height of cylinder)
or in short, V = πr(square)h
We have all the variables available, as radius is 15 ft and height is 45 ft the volume would be π*15*15*45 = 31808.63 cubic ft (using the approximated value of π as 3.14159).
The volume of water the tank can hold would be equal to the volume of the tank or 31808.63 cubic ft.
