Program to find area and circumference of circle using radius

radius = float(input("enter radius "))
pi = 3.1423
#circumference of circle
circum = 2*pi*radius
print("circumference of circle ",circum)

#area of circle 
area = pi*radius*radius
print("area of circle ",area)

#USING INBUILT FUNCTIONS
from math import pi
area1 = pi*radius*radius
circum1 = 2*pi*radius
print("area is ",area1)
print("circumference ",circum1)

Output

enter radius 4
circumference of circle  25.1384
area of circle  50.2768
50.26548245743669
