Answer:
The code to calculate the area of a circle is:
from math import pi
def circleArea(radius):
if radius > 0:
return pi * (radius ** 2)
else:
return None
if __name__ == '__main__':
radius = 5
print("Radius: {} Area: {}".format(radius,circleArea(radius)))
Explanation:
A detailed explanation of each line of code is given below.
#Define the number pi used to calculate the area
from math import pi
#We define a function that calculates the area of a circle
def circleArea(radius):
#Check if the radius is valid ( radius > 0) since there aren´t negative radius
if radius > 0:
#Compute the area formula for a circle
return pi * (radius ** 2)
else:
#Return None if the radius is invalid
return None
#Run the function we´ve defined
if __name__ == '__main__':
#Define a radius
radius = 5
#Call the function and parse the radius through it, then print the result
print("Radius: {} Area: {}".format(radius,circleArea(radius)))
