When a cylindrical tank is filled with water at a rate of 22 cubic meters per hour, the level of water in the tank rises at a rate of 0.7 meters per hour. Which of the following best approximates the radius of the tank in meters?  Choose the correct choice from the following choices: A) √10/2 B) √10 C) 4 D) 5 E) 10
V = pi(R^2)(H)   We have the Volume (22 cubic meters) and the Height (0.7 meters)...   22 = pi(R^2)(0.7)   pi = about 3.14   .7(pi) = about 2.2   22 = 2.2(R^2)   10 = R^2   \sqrt{10} = R   Final Answer:   √10
