How many gallons in a 24'X4' round pool?

Answer 1

None, until you fill it.

If you're asking for the equation of the volume of a cylinder, then find the area of the base by using the equation below. then, multiply the height of the cylinder by the area of the base.

A=(Pi)R2

V=BH OR V=[(Pi)R2]H

In your case, assuming that the height is four feet and the diameter is twenty-four feet,

A=12*12*3.141592653...

Therefore, A=452.389342032.

V={[(Pi)R2]=452.389342032}*4

Therefore, to answer your question, V=1,809.557368128'3. In U.S. gallons, that's 13,536.429142459.
