# Rahway Math Club Members Celebrate Pi Day

RAHWAY — Math Club members at Rahway High School joined with their peers at schools and museums across the country to celebrate Pi Day on March 14 (3.14).

Rahway’s celebration included two fundraisers. On Monday, students sold slices of pie. Later in the week, on Friday, the Math Club will hold a Pi(e) the Teacher event, where good-natured staff serve as the targets in a pie-throwing contest. Math teachers Vincent Vinci, Sarah Long and Toni D’Alessandro, security staff member Daniel Garay and even interim Principal John Farinella (a former math teacher) have offered to have the pies thrown at them.

The Rahway High School Math Club members, however, are not only involved with having fun, but also engage in service, tutoring fellow students in algebra and geometry twice monthly after school and all through exam periods.

Pi is chosen for the celebration because is widely used by engineers and students in various mathematical formulae. The symbol is commonly used to calculate the area of a circle through the formula, Area = Pi x radius2 (area of the circle equals pi times the radius of the circle squared), and to calculate circumference through the formula, Circumference = Pi x diameter (circumference of the circle equals pi times the diameter of the circle). Pi has been calculated to more than 1 trillion digits after the decimal. It is an irrational number, continuing infinitely without repeating. In 1706, Welsh mathematician William Jones first used the symbol for pi to represent the ratio of the circumference of a circle to its diameter.

Even one large technology corporation celebrates Pi Day.  Raytheon, in Waltham, Mass., send apple pies to math and science teachers in public middle and high schools in the communities surrounding the firm.  These pies are a thank you from the many engineers and scientists employed at Raytheon for math teachers’ work in encouraging tomorrow’s innovators.

Rahway High School students Emera De Los Santos, Bianca Anuforo, and Olivia Judah enjoy servings of pie in honor of Pie Day.
