How may gallons of water to fill a 12 ft round 36 inch deep pool?

Answer 1

First you have to find the capacity (cu ft volume) of the pool, then multiply by the number of gallons of water per cubic foot. V= (Pi x R²)(3). = (3.1416 x 36)(3) = 113.0976 x 3 = 339.2928 cu ft. There are 7.481 gal water per cu ft: 339.2928 x 7.481 = 2,538.25 gallons (to capacity). You will most likely use quite a bit less.
