Suppose that, for the sphere in the video, instead of being told how fast the ra dV = 4 cubic centimeters per dt the volume is increasing at a constant rate of %3D dr increasing at the instant when the radius is r = 10 centimeters? dt centimeters per second. Instead of thinking about the volume, suppose that we are interested in how th changing. Use the surface area formula S = 4rr to determine how fast the su %3D dr = 2 ce dt instant when the radius is r = 20 cm and the radius is increasing at
