A balloon and a bicycle A balloon is rising vertically above a level, straight road at a constant rate of 1 ft/sec. Just when the balloon is 65 ft above the ground, a bicycle moving at a constant rate of 17 ft/sec passes under it. How fast is the distance s(t) between the bicycle and balloon increasing 3 sec later?

A spherical balloon is inflating with helium at a rate of 64π ft3 min. How fast is the balloon's radius increasing at the instant the radius is 2 ft? Write an equation relating the volume of a sphere, V, and the radius of the sphere, r. (Type an exact answer, using π as needed.) Differentiate both sides of the equation with respect to t. dV dt = ( ) dr dt (Type an exact answer, using π as needed. Type an expression using r as the variable.) The balloon's radius is increasing at a rate of at the instant the radius is 2 ft. (Simplify your answer.)
