An oil tank has to be drained for maintenance. the tank is shaped like a cylinder that is 4 ft long with a diameter of 1.6 ft. suppose oil is drained at a rate of 1.7 ft³ per minute. if the tank starts completely full, how many minutes will it take to empty the tank? answer if you know how to do this question. you : )

It will take 4.7 minutes to empty the tank. This is because you first would have to find the area of the tank. In order to do that you would have to find the area of just the flat circle, so to do that you do the radius squared times pi. So take the diameter divide it by 2 And get 0.8 (radius) and then square it (multiply it by itself) and get 0.64 than multiply it by 3.14. Than take the answer to that and multiply it by the height (4) and than divide by 1.7 .

Hope that helped :)
