		Scanner s = new Scanner(System.in);
		System.out.println("nPlease enter the radius : ");
		//Author -> ITVoyagers, visit -> itvoyagers.in
		r = s.nextFloat();
		System.out.println("nnArea of Circle = " + pi * r * r);
		System.out.println("nnPerimeter of Circle = " + 2 * pi * r);
		
		System.out.println("nn");
