Chapter: Miscellaneous Last Updated: 13-08-2016 13:20:36 UTC

Program:

            /* ............... START ............... */
                
import java.util.Scanner;

public class JavaAreaCircumferenceCircle {

	static Scanner sc = new Scanner(System.in);

	public static void main(String args[]) {
		System.out.print("Enter the radius: ");
		double radius = sc.nextDouble();
		// Area = PI*radius*radius
		double area = Math.PI * (radius * radius);
		System.out.println("The area of circle is: " + area);
		// Circumference = 2*PI*radius
		double circumference = Math.PI * 2 * radius;
		System.out.println("The circumference of the circle is:" + circumference);
	}
}
                /* ............... END ............... */
        

Output

Enter the radius: 15
The area of circle is: 706.8583470577034
The circumference of the circle is:94.24777960769379

Notes:

  • The distance around a circle is called its circumference. The distance across a circle through its center is called its diameter.
