#include <iostream>

using namespace std;

#define PI_VAL      3.1415926535
int main()
{
  int nCaseCount = 0;
  double xVal = 0.0f;
  double yVal = 0.0f;
  cin >> nCaseCount;
  for ( int i = 0; i < nCaseCount; ++i )
  {
    cin >> xVal >> yVal;
    cout << "Property " << i + 1 << ": This property will begin eroding in year " 
      << (int)ceil( PI_VAL*(xVal*xVal + yVal*yVal) / 100.0) << "." << endl;
  } 
  cout << "END OF OUTPUT." << endl;

  return 0;
