In this article, we are going to write a java program to calculate the area of a circle. We will use the java Scanner class for taking radius input from the User

## Area of Circle

We can calculate area of circle by using following formula

**Area = pi * r*r**

Here pi = 3.14 , r is radius of circle

## Java Program to Calculate Area of Circle

### Steps to Calculate Area of Circle using Programming Language

- Take radius input from user
- Calculate Area of circle by using formula pi*r*r
- Print the Area of Circle

### Java Code for Area of Circle

```
package gangforcode;
import java.util.Scanner;
public class AreaofCircle {
public static void main(String[] args) {
final double pi = 3.14;
Scanner sc = new Scanner(System.in);
System.out.println("Enter the radius of Circle");
double radius = sc.nextDouble();
double area = pi*radius*radius;
System.out.println("Area of Circle = " +area);
}
}
```

## Output for java code:-

You can calculate the area of a circle in the same way in other programming languages like C, C++ Python, etc
