Java Program to Calculate Area And Circumference of Circle

---

In this java program we are going to calculate area and circumference of a circle. For this we will use below Formula to calculate area and circumference of a circle.

Area of circle = PI*Radius*radius;
Circumference of circle=2*PI*radius

Java Program to Calculate Area And Circumference of Circle

---

import java.util.Scanner;

class Circle

{

public static void main(String args[])

 {

    Scanner sc = new Scanner(System.in);

    System.out.print("Enter the radius of Circle: ");

   double radius = sc.nextDouble();


 /* Area of Circle = PI*radius*radius */

    double area = Math.PI * (radius * radius);

   System.out.println("Area of circle is : " + area);

 /* Circumference of Circle = 2*PI*radius */

  double circumference= Math.PI * 2*radius;

  System.out.println( "Circumference of the circle is: " +circumference) ;

}
