**Program to calculate area of circle**

This is a Java Program to Calculate and Display Area of a Circle.

Formula:

Area of circle=pi * r * r

Enter the radius of the circle as input.

Now we use the given formula to calculate the area of the circle using formula.

import java.util.Scanner; public class Area { public static void main(String[] args) { int r; double pi = 3.14, area; Scanner s = new Scanner(System.in); System.out.print("Enter radius of circle:"); r = s.nextInt(); area = pi * r * r; System.out.println("Area of circle:"+area); } }

**Program Output:**

$ javac Area.java

$ java Area

Enter radius of circle:24 Area of circle:1808.63999

I hope this post helps you to understand Area of circle and its implementation in Java programming language.

Keep coding 🙂
