An oil tank has to be drained for maintenance. The tank is shaped like a cylinder that is

3.5 ft long with a diameter of 1.4 ft. Suppose oil is drained at a rate of

1.5 ft3 per minute. If the tank starts completely full, how many minutes will it take to empty the tank?

Use the value 3.14 for π, and round your answer to the nearest minute. Do not round any intermediate computations.

Fidn volume

V=hpir^2

d/2=r

1.4/2=0.7=r

height=3.5

V=3.5*3.14*0.7^2

V=5.3851

1.5 times t=5.3851

divide both sides by 1.5

t=3.59

round

t=4

4 minutes
