By my calculations (and they could be wrong--English major here), it would hold 11,320 gallons.
Volume = πr2h = π(45.040848895006380022594105034422)2(40)
Approx 2.1 Imperial gallons = 2.5 US gallons.

The circumference = 15.85331 feet.Circumf. = Pi x sqrt (4 x V / Pi x H)where V = volumeandH = height
You need to tell us how deep it is.
