# Part 1

The volume of a sphere is 4/3πr3, where π has the value of "pi" given in Section 2.1 of your textbook. Write a function called print_volume (r) that takes an argument for the radius of the sphere, and prints the volume of the sphere.

 ✓ Call your print_volume function three times with different values for radius.

 ✓ Include all of the following in your Learning Journal:
    - The code for your print_volume function.
    - The inputs and outputs to three calls of your print_volume.
