Old puzzle with a twist

Consider the following popular riddle:

“An explorer walks one mile due south,
turns and walks one mile due west, turns again and walks one mile due
north. He finds himself back where he started. He shoots a bear, what
color is the bear?”

The answer found in most puzzle books is “White” since he must have started at the North Pole.

But in fact, he could have started in other place(s). Another possible starting location is 1+1/(2pi) miles north from the south pole. In this solution, he walks 1 mile south to be 1/(2pi) miles north of the south pole, then walks due west in a circle of circumference 1, and then north to his original starting location.

See if you can figure out every possible solution (assuming the Earth is a perfect sphere).

Fun pi facts

Using pi calculated out to only 39 decimal places would allow one to compute the circumference of the entire universe to the accuracy of less than the diameter of a hydrogen atom.



3.14 backwards is PIE.



The letter π is the first letter of the Greek word “periphery” and “perimeter.” The symbol π in mathematics represents the ratio of a circle’s circumference to its diameter. In other words, π is the number of times a circle’s diameter will fit around its circumference.



The first 144 digits of pi add up to 666 (which many scholars say is “the mark of the Beast”). And 144 = (6+6) x (6+6).



William Shanks (1812-1882) worked for years by hand to find the first 707 digits of pi. Unfortunately, he made a mistake after the 527th place and, consequently, the following digits were all wrong.



The first million decimal places of pi consist of 99,959 zeros, 99,758 1s, 100,026 2s, 100,229 3s, 100,230 4s, 100,359 5s, 99,548 6s, 99,800 7s, 99,985 8s, and 100,106 9s.
