How many liters of water are in a 27 foot round pool X 50 inches deep?

The volume of a cylinder is given by the formula \(V=\pi r^2 h\),where \(r\) is the radius of the cylinder and \(h\) is its height. In this case, the radius of the pool is 27/2 = 13.5 feet, and its height is 50 inches = 50/12 = 4.16 feet. So the volume of the pool is:

\(V=\pi (13.5)^2(4.16) = 740.922 \ cubic \ feet\)

To convert cubic feet to liters, we multiply by 28.31685:

\(740.922 \ cubic \ feet = 740.922 \ \ cubic \ feet \times 28.31685 = 20,935 \ liters\)

Therefore, the 27 foot round pool X 50 inches deep contains 20,935 liters of water.
