A cylindrical barrel is filled with Kerosene at a rate of 33 cubic meters per hour, the level of kerosene in the barrel rises at a rate of 0.11 meters per hour. Which of the following best approximates the radius of the barrel in meters?
Choose the correct answer: A) √105/11 B) √102/11 C) 12 D) 52 E) 10
Here's my re-worked solution:   volume = 33 = pi (r^2)(0.11)   33 = 22/7 (11/10)(r^2)   r = sqrt(105/11)   √105/11ns: √105/11
