1. The radius of a spherical balloon is increasing at a rate of 4 centimeters per minute. How fast is the surface area changing when the radius is 14 centimeters? Hint: The surface area is S = 4πr2. Rate of change of surface area = cm /min 2. The surface area of a spherical balloon is increasing at a rate of 22 centimeters squared per minute. How fast is the radius changing when the radius is 14 centimeters? Rate of change of radius = cm/min

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.)
