Question

How much gallons of water is in a round 18' above ground pool?

Answer 1

You need to know the diameter.  Go online to one of the pool supply sites. There should be a calculator there that will translate your pool size into number of gallons.

Answer 2

The long answer:

Volume = pi x radius squared x depth

= 3.14 x ( 9 x 9 ) x depth, where depth is in feet.

= 254.5 x [depth in feet] cubic feet

Then convert cubic feet to gallons ( x 7.481).

= 1903.7 x [depth in feet] gallons

If your pool is an average of 3 feet deep, that's

= 5711 gallons

Answer 3

radias x pi x depth

use this formula to get the correct answer.
