Java Program to Calculate Area and Circumference of Circle

Here you will get java program to calculate area and circumference of circle.

Formula used:

Area of Circle = 3.14 * radius²

Circumference of Circle = 2 * 3.14 * radius

import java.util.Scanner;

public class Circle {
	public static void main(String args[]){
		double radius, area, circumference;
		Scanner sc = new Scanner(System.in);
		
		System.out.println("Enter radius:");
		radius = sc.nextDouble();
		
		area = 3.14 * (radius * radius);
		circumference = 2 * 3.14 * radius;
		
		System.out.println("Area = " + area + "\nCircumference = " + circumference);
	}
}

Output

Enter radius:
3.5
Area = 38.465
Circumference = 21.98
