Pi Day

Pi Day: Why We Celebrate π (and Eat Pies)

Every year on March 14th, we celebrate Pi Day, a nod to the famous number π (Pi), which starts with 3.14. To mark the occasion, our school will be selling pies through the canteen.

What is Pi?

Pi (π) is the ratio of a circle's circumference to its diameter, and no matter the size of the circle, this ratio is always about 3.14159—though it never ends or repeats. Mathematicians have been intrigued by Pi for thousands of years, with early estimates from the Babylonians and Egyptians to modern-day supercomputers calculating trillions of digits.

Why Pi Matters

Pi isn’t just for math class—it’s used in real life, including:

• Designing bridges and buildings.

• Understanding sound waves and ocean tides.

• Calculating planetary orbits in astronomy.

• GPS technology for accurate distance tracking.

Cool Uses of Pi

• NASA Missions: Engineers use pi to calculate flight paths for space travel.

• Medical Imaging: MRI scanners rely on pi-based calculations.

• Cybersecurity: Pi helps with encryption and secure online transactions.

Pi and Pies: What’s the Connection?

Since pies are round, their circumference and area are calculated using π. The area of a pie is found using the formula:

Area = π × radius²

So, the bigger the radius, the more pie you get!

Get Involved: Buy a Pie!

To celebrate Pi Day, our school will be selling: Beef Mince; Chicken and Vegetable and Potato pies, as well as fruit pies with a scoop of ice cream. All proceeds will go toward funding the 2025 Beaufort Secondary College World Challenge Trip to Borneo.

So, grab a pie, support a good cause, and enjoy Pi Day!
