Object-oriented programming (OOP) allows us to create classes that encapsulate data and methods. This program demonstrates how to create a Python program that calculates the area and perimeter of a circle using a class.
Problem Statement
Write a Python program that defines a class for a circle, calculates its area and perimeter, and provides methods to access these values.
Python Program to Find the Area and Perimeter of a Circle using Class
import math
class Circle:
def __init__(self, radius):
self.radius = radius
def calculate_area(self):
return math.pi * self.radius ** 2
def calculate_perimeter(self):
return 2 * math.pi * self.radius
# Input
radius = float(input("Enter the radius of the circle: "))
# Creating a Circle object
circle = Circle(radius)
# Calculating area and perimeter
area = circle.calculate_area()
perimeter = circle.calculate_perimeter()
# Output
print("Circle with radius", radius)
print("Area:", area)
print("Perimeter:", perimeter)
