Hello everyone, welcome to **nkcoderz.com**. In this article we will going to discuss about Area of Circle Program In Python.

To calculate the area of a circle in Python, you can use the following formula:

```
area = pi * r**2
```

Here, “area” is the variable that will hold the result, “pi” is a constant representing the value of pi (approximately 3.14), and “r” is the radius of the circle. The “**” operator raises the value of “r” to the power of 2.

## Area of Circle Program In Python

To use this formula in a program, you will need to import the `math`

module, which provides mathematical functions, including the value of pi. Here’s an example of how you could use this formula to calculate the area of a circle with a radius of 5:

```
import math
def area_of_circle(r):
area = math.pi * r**2
return area
radius = 5
print(area_of_circle(radius))
```

## Output

78.53981633974483

This code would output the area of the circle with a radius of 5.
