dia=18ft
depth = 4 ft
radius=18/2ft=9ft
area of circle = pie * radius^2
= 22/7*9*9
=254.57142857
volume of O pool = area X depth
=254.57142857 X 4
=1018.2857142857142
(roundoff) = 1018.3 ftXftXft
=305.1 m XftXft
=305.1 X3.3375X3.3375
=3398.48m^3
=3398480dm^3
=3398480litre (1dm^3=1litre)
=745280.70175438596491228070175439 galleons

The answer is: 7,614 gallons
The first and 4th answers are good.
It takes 1017.88 cubic ft to fill the pool.
And there are 7.48 gallons in a cubic foot, so the answer is 7.48 x 1017.88 = 7,614 gallons
V(cubic ft) = pi x r^2 x h = pi x 81 x 4= 1017.88 cu. ft
r = 18/2 = 9ft. h = 4ft.

V = pi * r^2 * h
V = pi * 9^2 * 4 = pi * 81 * 4 = pi * 324 = 1017.88 cubic feet
Convert to cubic inches: 1017.88 cubic feet = 1758889.76 cubic inches (1728 cubic inches in a cubic foot)
Convert to gallons: 1758889.76 cubic inches = 7614.24 gallons (231 cubic inches in a gallon)

Let's see, I had a pool that was 12' x 3' and it took 1776 gal to fill.
Sooooo, I'd guess about 2500 gal. for yours.
