This supports us to use all the mathematical functions in Python programming. We can without providing PI value, directly using the math library for the imported value of PI and calculate the area of the circle. Then, calculate the area of the circle using the formula, and the value of the area is displayed using the print() function. r = float(input('Enter the radius of the circle: ')) So, we need to convert it to float first and store it in variable r. input() method reads user input as a string. Inputs are scanned using the input() function. In this program, Inputs (the radius of the circle) will be provided by the user. R = float(input('Enter the radius of the circle: ')) In the previous program, the radius is hardcoded in the program but in this program, the radius will be provided by the user.

print('Area of circle = ',area)ДЇind the area of circle where the radius is provided by the user Then, the value of the area is displayed using the print() function. Now, calculate the area of the circle using formula. In this program, we have hardcoded the value of radius in the source code. We will take the radius when declaring the variable, the value of the area will be calculated and stored in the variable, and finally, it will be displayed on the screen.

This is the simplest and easiest way to calculate the area of the circle in python. Program description:- Write a Python program to find the area of the circle. Now letвЂ™s see how we can implement the area of circle calculator in Python. The radius of the circle will be given and the python program will calculate the area of the circle using various methods.ДЄrea of circle = в„ј * radius * radius = в„јr 2 Area of Circle in Python | Here, we will discuss all possible methods to write a python program to calculate the area of the circle.
