# Java Program to Find the Area of the Cricle

In this article, we will learn to create a program that calculates the area of the circle using a java programming language.

## Area of Circle

**Area** = pi*r*r

where, pi = 3.14

r is the radius of the circle.

## Explanation

- First, we will create a function name area().
- area() takes the argument as a radius and returns the calculated area of the circle
- In the main() function, we take input of radius from the user and call the area() function.

## Solution

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | import java.util.*; class ar_cirlce { public static double area(int r){ double area; area = 3.14*r*r; return area; } public static void main(String args[]){ int radius; Scanner sc = new Scanner(System.in); radius = sc.nextInt(); System.out.println(area(radius)); } } |

## Output

5 78.5
