Finding Area of a Circle in Given Radius Using Java

Hi ALL,

Here I wrote a program for Finding Area of a Circle in Given Radius Using Java.

/**

public class area1 {

    public static void main(String arg[]){

        double radius;

        double area;

        System.out.println(" Enter the size of the radius: \t ");

        Scanner in=new Scanner(System.in);

        radius=in.nextDouble();

        area=radius*radius*3.14;

        System.out.println("The area of the Circle is "+area +" the radius of "

                + "circle is " +radius);

    }

}
