Java Program to Calculate Area and Circumference of Circle or Program to Calculate Area and Circumference of Circle in Java or simple java program to find area of circle or Java Program to Calculate and Display Area of a Circle or Java Program to calculate area and circumference of circle or Calculate Area / Circumference Of Circle Using Java Math.PI


Explanation:- 
Circumference of the circle is the distance around the circle. Below two formula are given with the help of both formulae you can find the Area and Circumference of Circle. We can calculate the circumference of the circle by given formula.

Circumference of Circle = 2 * π * r

Here PI (π) is a Greek Letter and r is a Radius (1/2 Of Diameter ) PI (π) = 3.141592653589793 Approx. It is a constant value for more about Circumference Click Here

import java.util.Scanner;
class circle
{
   static Scanner sc = new Scanner(System.in);
   public static void main(String args[])
   {
      System.out.print("Enter The Radius Of Circle: ");
      double radius = sc.nextDouble();
      
   double area = Math.PI * (radius * radius);
      System.out.println("Circle Area is : " + area);
      
   double circumference= Math.PI * 2*radius;
      System.out.println( "Circle Circumference is:"+circumference);
   }
}

 

Output:

Enter The Radius Of Circle: 50

Circle Area is : 7853.981633974483

Circle Circumference is:314.1592653589793
