Python Program to Find Area and Circumference of Circle
This python program calculates area and circumference of circle whose radius is given by user.
Following formula are used in this program to calculate area and circumference of circle:
Area = πr2
Python Source Code: Circle Area & Circumference Calculator
# Finding area and circumference # importing math module for PI import math # Reading temperature in Celsius radius = float(input('Enter radius of circle: ')) # Calculating area and circumference area = math.pi * radius ** 2 circumference = 2 * math.pi * radius # Displaying output print('Area = %0.4f.' % (area)) print('Circumference = %0.4f.' % (circumference))
Python Area & Circumference of Circle Output
Enter radius of circle: 5 Area = 78.5398. Circumference = 31.4159.
