PORTLAND, Ore. (KOIN) — Local baking icon Marissa Troeschel is back on AM Extra, this time to help celebrate March 14, Pi Day!
Not familiar with Pi Day? Well, the recognition began in 1988 at the Exploratorium. The numbers in the date (3/14) match the first three digits of the mathematical constant pi (π).
