Answer»

class Circle:

pi=3.14

def_init_(self,radius)

self.radius=radius

def area(self):

return Circle.pi*(self.radius**2)

def circumference(self):

return 2*Circle.pi*self.radius

r = int(input(“Enter Radius:”))

C=Circle(r)

print(“The Area = ” ,C.area( ))

print(“The Circumference = ” , C.circumference( ))

Output:

Enter Radius: 5

The Area = 78.5

The Circumference = 31.400000000000002
