Pentagon Trivia

[Missileer]

It's as yet unsolvable as far as I know. The original question years ago was if you had a string tied around the earth, then raised the string one inch where it was exactly one inch from the surface, all the way around, what would the circumference of the string be?

Theoretically, it's solvable if you,
A. know the circumference of the earth.
B. Assume a perfectly round earth.

Use Circumference equals diameter multiplied by Pi. Or C=d x Pi. The trick is to imagine a circle within a circle where the outside circle radius is only one inch more than the radius of the inside circle, or the diameter will be two inches longer.

So by raise it one inch, you mean to hold it out from the outer walls of the Pentagon one inch and determine the circumference? In essence determining the circumference if the pentagon were to grow by one inch. Right?

That's right, remember this is a magic string and the pentagon has perfectly smooth sides. Now, Cpent = ?
