How many gallons does a 14 x 3 ft round pool hold? - Answers

I will assume the round pool is in fact circular, and that the given dimensions are 14ft diameter and 3ft depth.Firstly, you need to find out the volume of the pool. This is given by V=(pi*r2)*d where r is the radius of the pool and d is the depth of the pool. This formula represents the area of the circle times its depth, which is the volume of a cylinder. Radius is also half the diameter, so 7ft. Therefore, the volume is V=[pi*(7ft)2]*(3ft)=461.81 ft3.Next, you need to know what a gallon is in cubic feet (ft3). Google gives a conversion factor of 1 US gallon = 0.133681 ft3.To convert the units multiply 461.81ft3 * (1gal/0.133681ft3) = 3454.60 gallonsMy numbers may not be exactly correct, but the method should be sound. Hope that helps.
