# Python Program to Find Circumference of Circle

Circumference of a circle is defined as length of perimeter of circle. Mathematically, circumference of a circle having radius r will be 2πr. Quite simeple, so we need to just code this simple mathematical formula as Python Code.
Python Code for Finding Circumference of Circle

``````# Calculate circumference of a Circle

# Importing Python's Math Module
import math

# Using value of pie inside math inside
π = math.tau

# Circumference of circle = 2πr
circumference = 2 * π * radius

# Printing out circumference of circle
print("Circumference of circle is => ", circumference)``````

Output of Above Code

``````Enter radius of circle => 5
Circumference of circle is =>  62.83185307179586``````
