29. Write a python program to find the area and circumference of circle using function.

from math import pi

def area_circum(r):
    A = pi*r**2
    C = 2*pi*r

    print(f'Area is {A} and circumference is {C}')

if __name__ == "__main__":
    n = float(input('Enter the radius: '))
    area_circum(n)
