Python program to calculate circumference of circle

The program to calculate circumference of circle in python is as follows:

 

# Owner : TutorialsInhand Author : Devjeet Roy
 
r = float(input('Enter radius: '))  
   
circumference = (2 * 22 * r) / 7

print("The circumference is:", round(circumference,2)) 

The output of the python program to calculate circumference of circle is as follows :

 

PS C:\Users\DEVJEET\Desktop\tutorialsInHand> python code.py
Enter radius: 5
The circumference is: 31.43

Few important tips about this program:

1. As mentioned earlier, the input() function returns the user input in string format. We have used float() here to type convert the string to float type to perform mathematical computations.

2. The formula for finding the circumference of a circle is 2 x PIE x radius
