Assume that the radius r of a sphere is expanding at a rate of 80 cm/min. The volume of a sphere is V = ar'and its surface area is 4rr. Determine the rate at which the surface area is changing with respect to time at t = 2 min, assuming that r = 10 at t = 0. (Use symbolic notation and fractions where needed.) dA cm-/min dt
