I have a round tank that is 114in round by 40in tall how many gallons does it hold?
:
Find the radius from the circumference (114" around)
2%2Api%2Ar+=+114
r = 114%2F%282%2Api%29
r = 18.14366" is the radius
:
Find the vol: V+=+pi%2Ar%5E2%2Ah
:
V+=+pi%2A18.14366%5E2%2A40
V = 41,367.55 cu/inches
:
Convert cu/in to gallons
41367.55 * 4.329(10^-3) = 179.1 gallons
