radius=float(input("Enter radius of the circle:"))
print("1.Calculate Area")
print("2.Calculate Perimeter")
choice=int(input("Enter your choice(1 or 2):"))
if choice==1:
area=3.14159*radius*radius
print("Area of circle with radius", radius ,"is", area)
else:
perimeter=2*3.14159*radius
print("Perimeter of circle with radius", radius, "is", perimeter)Output 1:
Enter radius of the circle:5
