This number's hexadecimal representation can be computed using the BBP spigot algorithm. By applying the method of exhaustion, Archimedes bounded this value above and below using a 96-gon. This number is the square of the Gaussian integral. A sixth of the square of this number equals the sum of the reciprocals of the perfect squares. This number is one-fourth the number of steradians in a sphere. This irrational number is the period of the tangent function and also the area of the unit circle. For 10 points, name the ratio of the circumference and diameter of a circle,
