Santa Rosa students get early start on Pi Day
Students at Santa Rosa Middle School on Friday got a head start on Saturday’s Pi Day.
As part of “Approximately Pi Day,” students paid to throw pies at their math teachers, including Gloria Hurtado, girding for the throw above. At right, Hurtado lifts her goggles to wipe away pie filling.
Money raised during the event will go toward a seventh-grade field trip.
Pi Day, usually a once-in-a-year calendar event, this time has a once-in-a-century twist. Today is 3-14-15, the first five digits of the mathematical constant pi: 3.141592653. The sequence won’t occur again until March 2115.
The Petaluma Pie Company is among bakeries to capitalize in recent years on the quirky holiday.
