Well, in the below java program user enters radius as input. Next we use area of circle formula.

// area = pi * r * r where r is the radius of a circle

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

**Output:**

Please enter radius of circle : 5

Area of circle : 78.5
