## Java Program to Calculate the Area of Circle

In this program, we will learn to calculate and display the area of a circle. To calculate the area of the circle we have to use a formula that is: (22*r*r)/7. Here “r” means the radius of the circle.

### Algorithm to Calculate the area of the circle

1. import java.io.*;
2. import java.util.*;
3. create class Area
4. public static void main(String[] args)
5. Scanner ob = new scanner (System.in)’
6. double r;
8. r = ob.nextInt();
9. double area = (22*r*r)/7.
10. System.out.print(” Area of the Circle is: ” + area);

### Source Code to Print the area of Circle

import java.io.*;
import java.util.*;
class Area
{
public static void main(String []args)
{
Scanner ob=new Scanner(System.in);
double r;
System.out.println(“enter value r”);
r=ob.nextInt();
double c = (22*r*r)/7;
System.out.println(“area of circle: ” +c);
}
}
