Part 1

The volume of a sphere is 4/3r³, where has the value of "pi" given in Section 2.1 of your textbook. Write function calledprint_volume (r)that takes an argument for the radius of the sphere, and prints the volume of the sphere.

Call yourprint_volumefunction three times with different values for radius.

Include all of the following in your Learning Journal:

• The code for yourprint_volumefunction.
• The inputs and outputs to three calls of yourprint_volume.

Part 2

Write a function that illustrates a feature that you learned in this unit. The function must take at least one argument.
