Here's a formula for round pools:
distance across*distance across*depth*5.9
for rectangles:
length*width*depth*7.5
or for a deep end:
length*width*((shallow end depth + deep end depth)/2)*7.5
so in your case, 15*15*4*5.9=5000 gallons
Volume Pi x r squared x 4 (depth) Pi = 3.14115926535 r = 1/2 Diameter = 7.5 depth = 4 gallons per cubic foot 7.48 3.14 x (7.5 x 7.5) x 4 x 7.48 = 5284.62 gallons Y-THINK-Y
The volume would be pi*r^2*d = 3.14*7.5^2*4 or about 707 cubic feet. This converts to 5289 gallons. This assumes the water is actually four feet deep which means the pool is a bit higher.
If this is a round pool 15 feet across and four feet deep, the maximum water capacity (filled to the very top) is 5,288.7 gallons.
Multiply 15 x 15 x 4 x 5.9 = 5,310 gallons in the pool
21,205.75 gallons
around 5 000 gals

Twelve feet of water in a 10-foot round pool is approximately 7,080 gallons.
Exactly 5264.1669 gallons
Three feet of water in a 12-foot round pool is about 2,550 gallons.

An 18-foot round pool with 3 feet of water contains 5,734.8 gallons of water. If you fill it to 4 feet deep it increases to 7,646 gallons of water.
That all depends on how deep the water has to be, which the question neglects to specify.
(3.5 feet) * PI * ((9 feet)^2) = 6 662.46122 US gallons
