Area of a circle is defined as region occupied by it, mathematically it can be calculated using **radius of circle** using formula = πr^{2} quite simple just need to program **multiplication of pie, square of radius** that’s **Area of Circle**.

Let’s see Python Code for Calculating area of a circle.

```
# Finding area of circle using Python
# Import Python's Math Module
import math
# Accessing value of Pie from Math Module
π = math.tau
# Ask user for radius of circle
radius = float(input("Enter radius of circle => "))
area_of_circle = π * (radius**2)
print("Area of circle is =>", area_of_circle)
```

**Output of Above Code**

```
Enter radius of circle => 5
Area of circle is => 157.07963267948966
```
