CalculusQ&A Library2. Suppose that two circles have the same center. One has radius 2 cm. and the other has radius10 cm. Suddenly, the circles begin to expand. The radius of the smaller circle increases at a rateof 4 cm/sec. The radius of the larger circle increases at a rate of3 cm/sec.a) How fast is the area between the circles changing 6 seconds later? Put units of measure onyour answer.b) Is the area increasing or decreasing at that time? Support your answer.Question
