Source code of Python program to find the area and circumference of Circle
class Circle:
PI = 3.142
def __init__(self, radius):
self.radius = radius
def area (self):
return (Circle.PI * self.radius * self.radius)
def circumference(self):
return (2 * Circle.PI * self.radius)
r = int(input("Enter the radius of circle"))
c1 = Circle(r)
print ("The area of C1 circle is: ", c1.area())
print ("Circumference of C1 Circle is: ", c1.circumference())
print("")
r = int(input("Enter the radius of circle"))
c2 = Circle(r)
print ("Area of C1 circle is: ", c2.area())
print ("Circumference of C1 Circle is: ", c2.circumference())Output:
Enter the radius of circle 5
The area of C1 circle is: 78.55
Circumference of C1 Circle is: 31.419999999999998
Enter the radius of circle 6
The area of C1 circle is: 113.112
Circumference of C1 Circle is: 37.704
