	public static void main(String args[])
	{
		my_1005();
	}
	static void my_1005()
	{
		Scanner in = new Scanner(System.in);
		int n = in.nextInt();
		double[] a = new double[n];
		double[] b = new double[n];
		int m = 0;
		while( m < n )
		{
			a[m] = in.nextDouble();
			b[m] = in.nextDouble();
			m++;
		}
		
		m = 0;

		double area ;

		while( m < n )
		{
			area = Math.PI * (a[m]*a[m] + b[m]*b[m]) /2 ;
			System.out.println("Property "+(m+1)+": This property will begin eroding in year "+((int)area/50 + 1)+"."); 
			m++;
		}
		System.out.println("END OF OUTPUT.");
