✦ Synopsis
Approximating 7r and attempting to square the circle have a long and interesting history. In 1875, C. L. Dodgson began work on a computationally simple approximation method for would-be circle squarers that would convince them of the futility of their attempts. Relating the earlier geometric and the newer analytic approaches in a practical way, this method produces an accurate approximation for 7r efficiently.
