Do in Python

Answer 1

The expression written in the given print() calls are extracted into the function calculate_volume() and the existing calculations in the print() are replaced by the

function calls.

The complete code is given as follows:

#Define the function calculate_volume() having two parameters

#radius and height.

def calculate_volume(radius, height):

   

    #Initialize a variable PI with the value 3.14159.

    PI = 3.14159

    #Calculate the volume of cylinder by using the

    #formula PI * (radius^2) * height by placing the

    #value of PI, radius, and height value in this

    #formula.

    volumeOfCylinder = PI * (radius ** 2) * height

   

    #Return the volume of cylinder calculated above.

    return volumeOfCylinder

#Call the function calculate_volume() by passing different

#arguments.

print(calculate_volume(1, 2))

print(calculate_volume(5, 1))

print(calculate_volume(2, 3.1))
