Assuming your pool is round about 800 gallons.
1,770 gallons.
15,320.1 US gallons of water.
3384 gallons for every foot deep it is.
About 17,950 gallons.
9,440 gallons.
398.7 gallons.
169
42in.
300 gallons.
13ft equates to approximately 0.0025 mile; 1/400 mile.
The answer is about 2,979 gallons if you fill the pool exactly 3 feet deep. To get the answer you figure out the square feet in the 13 foot circle using the formula: Area = Pi times radius squared Pi is approxametly 3.142 Radius is 6.5 6.5 X 6.5 X 3.142 = 132.7495 square feet 132.7495 X 3= 398.2485 cubic feet 1 cubic foot holds 7.48 gallons 7.48 X 398.25= 2,978. 91 which rounds up to 2,979 gallons
