Learning Journal volume functionalities

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 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 yourprint_volumefunction.
The inputs and outputs to three calls of yourprint_volume.
Part 2
Write your own 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.Do not copy a function from your textbook or the Internet.
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.
