Python program

Python Program to Create a Class and Compute the Area and the Perimeter of the Circle .

import math
class circle():
def __init__(self,radius):
self.radius=radius
def area(self):
return math.pi*(self.radius**2)
def perimeter(self):
return 2*math.pi*self.radius

r=int(input("Enter radius of circle: "))
obj=circle(r)
print("Area of circle:",round(obj.area(),2))
print("Perimeter of circle:",round(obj.perimeter(),2))

OUTPUT:-

Case 1:
Enter radius of circle: 5
Area of circle: 78.54
Perimeter of circle: 31.42

Case 2:
Enter radius of circle: 10
Area of circle: 314.16
Perimeter of circle: 62.83
