Part 1

The volume of a sphere is 4/3r³, where has the value of "pi" given in Section 2.1 of your textbook. Make a 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

Make a function that illustrates a feature that you learned in this unit. The function must take at least one argument. The function should be your own creation, not copied from any other source.

Include all of the following in your Learning Journal:

• The code for the function that you invented.
• The inputs and outputs to three calls of your invented function.
• A description of what feature(s) your function illustrates.
