Java Program to Calculate Area of Circle

In this article, we are going to write a java program to calculate the area of a circle. We will use the java Scanner class for taking radius input from the User

Area of Circle

We can calculate area of circle by using following formula

Java Program to Calculate Area of Circle

Steps to Calculate Area of Circle using Programming Language

• Take radius input from user
• Calculate Area of circle by using formula pi*r*r
• Print the Area of Circle

Java Code for Area of Circle

package gangforcode;

import java.util.Scanner;
public class AreaofCircle {

    public static void main(String[] args) {
        final double pi = 3.14;
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter the radius of Circle");
        double radius = sc.nextDouble();
        double area = pi*radius*radius;
        System.out.println("Area of Circle = " +area);
    }
}

Output for java code:-

You can calculate the area of a circle in the same way in other programming languages like C, C++ Python, etc
