A spherical balloon is inflating with helium at a rate of 128x ft / min. How fast is the balloon's radius increasing at the instant the radius is 4 ft? How fast is the surface area increasing? The balloon's radius is increasing at a rate of ft / min at the instant the radius is 4 ft. (Simplify your answer.) The surface area is increasing at a rate of ft/ min at the instant the radius is 4 ft. (Type an exact answer, using t as needed.)
