Given a point in the target (defined by its [Cartesian coordinates][cartesian-coordinates] `x` and `y`, where `x` and `y` are [real][real-numbers]), calculate the correct score earned by a dart landing at that point.

~~~~exercism/note
To find which circle a dart falls in, you can compute the [distance][distance-formula] from the point to the center (0, 0) and compare it against each circle's radius.
