A cylinder 30 inches in diameter and 48 inches tall will have a volume of 33929 cubic inches. V=PI*r*r*H (V=3.1416*15*15*48) That volume is equal to 146.9 gallons (USA). (1 gal = 231 cubic inches)
4 gallons = 64 cups, as 1 gallon = 16 cups.
cylinder = pi x r(squared) x h

7 gallons = 56 pintsTrue for both UK/imperial gallons and US liquid gallons.
4 r=48
Assuming 60 foot diameter ( 30 foot radius)>Volume (US gallons) = (pi * r * r * depth) / 0.1336805556 = 126,904.0>Volume (UK gallons) = (pi * r * r * depth) / 0.16054365324 = 105,669.7
