## Python Code: Find Area of Circle easily

This is a general approach to find the area of a circle in Python, the logic will work find in other programming languages also.

Copy
``````radius = float(input("Enter the radius of circle: "))
Output
```Enter the radius of circle: 5
Area of circle with radius 5.0 is 78.5```

The logic of this code is simple.
