The posted coordinates have nothing to do with the puzzle, no need to attempt to go there.
Since Pi is never repeating and never ending every combination of numbers should appear somewhere, including, you guessed it, coordinates. Start from the digit indicated and fill in the coords, start counting after the decimal point.
N 38 79,889th digit of pi.
W 122 174,346th digit of pi.
π is a mathematical constant that is the ratio of any Euclidean circle's circumference to its diameter. π is approximately equal to 3.14. Many formulae in mathematics, science, and engineering involve π, which makes it one of the most important mathematical constants. For instance, the area of a circle is equal to π times the square of the radius of the circle.
π is an irrational number, which means that its value cannot be expressed exactly as a fraction having integers in both the numerator and denominator (unlike 22/7). Consequently, its decimal representation never ends and never repeats. π is also a transcendental number, which implies, among other things, that no finite sequence of algebraic operations on integers (powers, roots, sums, etc.) can render its value; proving this fact was a significant mathematical achievement of the 19th century.
