# Java Program for calculating the Area of a circle

## Area of a circle using Java :

Here, in this page we will write the program to find area of circle using java. The area of a circle is the number of square units inside the circle. If we know the radius of the circle, then we can directly calculate the area by using a standard formula, ## Working:-

• Calculate the area by using the standard formula:

or

A = π * (diameter * diameter)/4

• Print the result.

### Code in Java using Radius

```//Java program to calculate area of a circle
import java.util.Scanner;
public class Main
{
public static void main(String[] args)
{

//formula for area of a circle
System.out.println(area);

}
}```

`153.86`

### Code in Java using Diameter

```//Java program to calculate area of a circle
import java.util.Scanner;
public class Main
{
public static void main(String[] args)
{

double d = 14;

//formula for area of a circle
double area = (3.14 * d * d)/4;
System.out.println(area);

}
}```

`153.86`
