Example Question #741 : Rate Of Change

A spherical balloon is being filled with air. What is the rate of growth of the sphere's volume when the radius is 20 and the rate of change of the radius is 1?

 

Possible Answers:

Correct answer:

Explanation:

Let's begin by writing the equation for the volume of a sphere with respect to the sphere's radius:

The rate of change can be found by taking the derivative of each side of the equation with respect to time:

Now given our problem conditions, the radius is 20 and the rate of change of the radius is 1, we can solve for the rate of change of our volume:
