Water is poured into an empty cylindrical tank at a constant rate. In 10 minutes, the height of the water increased by 7 feet. The radius of the tank is 10 feet. What is the rate at which the water is poured?
(A) \(\frac{11}{8} \pi\) cubic feet per minute.
(B) \(\frac{11}{3} \pi\) cubic feet per minute.
(C) \(\frac{7}{60} \pi\) cubic feet per minute.
(D) \(11 \pi\) cubic feet per minute.
(E) \(70 \pi\) cubic feet per minute.

We can use the work formula, work = rate x time
We need to find the rate. Time is given as 10 minutes.
The work done here is filling the tank, so, we find the volume of the tank, which is pi * r * r * h = rate * 10
Once, we substitute radius as 10 and height as 7, we can get the value of rate, which is 70*pi
