Hi,

cylinder 5ft long with a diameter of 1.5ft (radius of .75 ft)



V = +pi%2A%28r%5E2%29h+= 3.14%28%28.75%29%5E2%295+=+%288.8ft%5E3%29 | Note

a pump pours gas at the rate of 2 ft^3 per minute.

%288.8ft%5E3%29%2F%282ft%5E3%2Fmin%29+=+%284.4min%29+ time it takes to fill the empty tank with that pump
