Slip 20 - A) Write a python program to create a class Circle and Compute the Area and the circumferences of the circle.(use parameterized constructor)

 Solution :

class Circle():
def __init__(self, r):
self.radius = r def area(self):
return self.radius**2*3.14

def circumference(self):
return 2*self.radius*3.14 radius=int(input("Enter radius of circle: "))
NewCircle = Circle(radius)
print(NewCircle.area())
print(NewCircle.circumference())

Output:
