# Java Program to find area of Circle (Use Constant)

Get radius of circle and find area of circle.

Sample Input 1:

4

Sample Output 1:

50.24

#### Program or Solution

import java.util.*; class Circle { public static void main(String args[]) { double radius; double area; Scanner sc=new Scanner(System.in); System.out.println("Get the radius of Circle and find area of Circle"); System.out.println("Enter The Input 1:"); radius=sc.nextDouble(); area=3.14*radius*radius; System.out.println("The Output 1 Is:\n"+area); } }

#### Program Explanation

Get radius of a circle (using scanner class) Calculate area by multiplying pi and radius and radius (area =pi*radius*radius) (pi is 3.14 , global constant) Print area (using system.out.println)
