# Java Program to Find Area of a Circumscribed Circle of a Square

In the previous article, we have seen Java Program to Check if a Given Circle Lies Completely Inside the Ring Formed by Two Concentric Circle

In this article we will discuss about how to Find Area of a Circumscribed Circle of a Square using Java programming language.

## Java Program to Find Area of a Circumscribed Circle of a Square

Before jumping into the program directly, let’s first know how we can Find Area of a Circumscribed Circle of a Square.

Explanation:

Formula to Find Area of a Circumscribed Circle of a Square: (pi*side*side)/2

Example:

When side=2

Area = (pi*side*side)/2

= (3.14*2*2)/2

= 6.28

Let’s see different ways to Find Area of a Circumscribed Circle of a Square.

### Method-1: Java Program to Find Area of a Circumscribed Circle of a Square By Using Static Value

Approach:

• Declare the value for side of the square.
• Use the formula (pi*side*side)/2 to calculate the area.
• Then print the result.

Program:

import java.util.Scanner;
public class Main
{
public static void main(String[] args)
{
// Static initialization of side of the square
double pi = 3.14;
double side = 60;
// Prints result of the square
System.out.println("Area of the square "+(pi*side*side/2));
}
}

Output:

Area of the square 5652.0

### Method-2: Java Program to Find Area of a Circumscribed Circle of a Square By User Input Value

Approach:

• Take user input the value side of the square.
• Use the formula (pi*side*side)/2 to calculate the area.
• Then print the result.

Program:

import java.awt.Point;
import java.util.Scanner;
import static java.lang.Math.*;

public class Main
{
public static void main(String[] args)
{
Scanner scan = new Scanner(System.in);
// Asking the user to input the side of the square
System.out.println("Enter the side of the square");
double pi = 3.14;
double side = scan.nextInt();
// Prints result of the square
System.out.println("Area of the square "+(pi*side*side/2));
}
}

Output:

Enter the side of the square
6
Area of the square 56.519999999999996
