The formula for the volume of a sphere is S = 4 3 πr3, where r (in feet) is the radius of the sphere. Suppose a spherical snowball is melting in the sun. (a) Suppose r = 1 (t + 1)2 − 1 15 , where t is time in minutes. Use the chain rule, dS dt = dS dr · dr dt , to find the rate at which the snowball is melting. dS dt = (b) Use the results from part (a) to find the rate (in ft3/min) at which the volume is changing at t = 1 min. (Round your answer to four decimal places.) ft3/min
