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.
