The gas tank of a truck cylinder is 4 ft long with a diameter of 2.5ft.
At the gas station, a pump pours gas at the rate of 3ft cubed per minute.
How many minutes does it take to fill the empty tank with that pump?
:
Find vol of a cylinder V+=+pi%2Ar%5E2h
r = 1.25 ft
V+=+pi%2A1.25%5E2%2A4
V = 19.635 cu ft
:
time = 19.635%2F3
t = 6.545 minutes
