Chris labels every lattice point in the coordinate plane with the square of the distance from the point to the origin (a lattice point is a point such that both of its coordinates are integers). How many times does he label a point with the number 25?

 

1st: ElectrivPavlov- 5 points

2nd: ilorty- 3 points
