An upright cylindrical tank with radius 7 m is being filled with water at a rate of 4 m3/min. How fast is the height of the water increasing? (Round the answer to four decimal places.)
A = pi * r^2 = 49 pi
(4 m^3 / min) / 49 pi m^2
= .2565 m / min
Can you plz help me with this and correct me because it may not be correct answer.
