Directions: Work in your small group to complete this worksheet. Return the completed worksheet along with the homework exercises at the beginning of next class. All answers must be justified and work shown for full credit. Explanations should be written using complete sentences on the lines provided. 1. A rock is thrown into a lake causing a wave to ripple outward. Suppose the radius of the circle bounded by the rippling is changing at a rate of 2 m/s at the moment when the circle's radius is 3 m. Determine how fast the area of the circle is changing at this same moment. a) Draw a picture and be sure to label it appropriately. b) Write an equation relating the area of the circle and the radius. c) Differentiate with respect to time. A= TT12 d dt d) How fast is the area of the circle changing when the radius is 3 m and changing at a rate o 2 m/s?
