Oil is poured in a cylindrical barrel at a rate of 5 cubic meters per hour, the level of oil in the tank rises at a rate of 1 meters per hour. Which of the following best approximates the radius of the tank in meters?	Choose the most appropriate option:
A) √35/22
B) √10/3
C) 4
D) 5
E) 10
Here's my re-worked solution:   volume = 5 = pi (r^2)(1)   5 = 22/7 (1)(r^2)   35/22 = r^2   r = sqrt(35/22)   √35/22ns: √35/22
