Name: November 6, 2009 Fall 2009 Math 113 Exam #2 1. An asteroid hits the Atlantic Ocean and creates an expanding circular wave. If the area enclosed by this wave increases at the rate of 200 km 2 /min, how fast is the diameter of the wave expanding when its radius is 20 km? 2. Suppose 10 bacteria are left to grow in a petri dish. At least for the first few hours, the rate of population growth of this bacterial culture will be proportional to the size of the culture. If there are
