Python

Circle Area and Circumference

Write a program that calculates the area and circumference of a circle given its radius.

import math

class Circle:
    def __init__(self, radius):
        self.radius = radius

    def circumference(self):
        return 2 * math.pi * self.radius

    def area(self):
        return math.pi * (self.radius ** 2)

# Driver code to test the Circle class
radius = 5
circle = Circle(radius)
print("The circumference of the circle is:", circle.circumference())
print("The area of the circle is:", circle.area())

note

To compile and run the program, you can use the following commands:

python3 foo.py
