Java program to calculate Area and Circumference of a Circle



A simple Java program to calculate Area and Circumference of a Circle by taking radius as input

import java.util.Scanner;

public class AreaAndCircumferenceOfCircle {

	public static void main(String args[]) {
		System.out.print("Enter the Radius: ");
		Scanner sc = new Scanner(System.in);
		double radius = sc.nextDouble();
		sc.close();

		double area = Math.PI * (radius * radius);
		System.out.println("The Area of circle is: " + area);

		double circumference = Math.PI * 2 * radius;
		System.out.println("The Circumference of the circle is:" + circumference);
	}

}

Output

Enter the Radius: 12
The Area of circle is: 452.3893421169302
The Circumference of the circle is:75.39822368615503
