h2o volume of my pool?

Sorry for this seemingly easy question but I have been given or calculated three different numbers. I have a 30' X 52" AG pool. Flat bottom and actual water depth is 45". My owners manual says I have around 23000 gallons, someone here estimated 16000 gal and I calculate about 18000gal. Any help or advice would be great!
Thanks,
Dave

You are at about 19,800 gallons according to Bleachcalc.

I get 19,791 gallons.

15 squared * pi * depth of 3.75 feet * 7.47.

If the actual water depth was 52" it would be 22,693 gallons.

round pool....19,800

thanks everybody! You guys are great!

Actually that should be * 7.48.

So at 45" you have 19,817 and at 52" you would have 22,724. That's probably why the manual shows 23,000.
