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?
Answer/Solution
√105/11
Steps/Work
Here's my re-worked solution:
volume = 33 = pi (r^2)(0.11)
33 = 22/7 (11/10)(r^2)
r = sqrt(105/11)
Ans: A
volume = 33 = pi (r^2)(0.11)
33 = 22/7 (11/10)(r^2)
r = sqrt(105/11)
Ans: A
