Answer to Question #330942 in Python for Labtec

Question

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.

Answer 1

import math


def print_volume(r):
    r = float(r)
    volume = 4.0/3.0 * math.pi * (r**3)
    print("Volume: " + str(round(volume, 2)))


for i in range(3):
    radius = input("Enter Radius: ")
    print_volume(radius)
