Every year on March 14, math enthusiasts and bargain hunters alike unite to celebrate Pi Day, a holiday dedicated to the mathematical constant pi, approximately equal to 3.14159. While pi represents the ratio of a circle's circumference to its diameter and has endless applications in science and engineering, it also inspires creative promotions from restaurants offering discounts on circular foods like pizza, pie, and cookies.
