Holaaa Mate

Answer:

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

Formula:

Perimeter of circle=pi * radius * radius

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);

}

}

Output:

$ javac Area.java

$ java Area

 

Enter radius of circle:5

Area of circle:78.5
