Pi-Day and Why it Matters


There are infinite ways to show children how math factors into their everyday lives. On March 14 – 3.14, or Pi Day – Raytheon Company (NYSE: RTN) is serving up a slice of proof that numbers are all around  them.

Raytheon is celebrating the world’s most famous never-ending number by delivering pies to Boys & Girls Clubs around the country and dishing out fun facts about the trusty, time-honored  decimal.

Pi dates back some 4,000 years, and it is commonly used to calculate the area of a circle. The number represents the ratio of the distance around a circle (circumference) to the distance across its center (diameter). Pi begins with 3.14 and goes on infinitely. To print out a billion decimal values in 12-point font would require a piece of paper long enough to stretch from Kansas to New York  City.

This year the chance to celebrate is truly once in a lifetime – with a sequential time occurring on 3/14/15 at 9:26:53 in the morning and the evening! Join Raytheon in encouraging the boys and girls in your life to join the Pi-arty:

  • Share our MathMovesU Pi Day quiz, fact sheet, infographic and video. It is all here in our Pi Day toolkit
  • Bake a pie with the student in your life – a great example of fractions at work – and deliver it to a science, technology, engineering or math teacher to say “thank you”
  • Tweet or post a photo with #mathmovesu and #piday of your favorite math or Pi t-shirt– or take time to make one
  • Wish someone a “Happy Pi Day” with our Pi Day eCards

Pi Through the Ages
Pi is widely used by engineers and students to solve math problems. The pi symbol is commonly used to calculate the area of a circle: the area of the circle equals pi times the radius of the circle squared. The earliest written approximation of pi dates back some 4,000 years. An ancient Greek mathematician from Syracuse, Sicily later discovered the first three digits of pi. Do you know his name? For the answer and more fun facts about pi, check out Raytheon’s infographic: “Happy Pi  Day.”
