Pi is a mathematical constant that is the ratio of a circle's circumference to its diameter. It is an irrational number and its decimal representation never ends or settles into a permanent repeating pattern. The current record for the decimal expansion of pi, if verified, stands at 5 trillion digits.
Blauwkamp challenged her students to calculate pi by measuring the circumference and diameter of circular objects in the classroom with the winning team getting to pie the teacher with a whipped cream pie.
The team of Alyssa Weitzel and Charisma McDonald calculated pi exactly from their circle and "pi'd" their teacher to the cheers from classmates.
