Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.
Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits.
You may remember the formula from high school geometry:
The area of a circle.
A = πr2
Where ‘r’ is the radius (distance from the center to the edge of the circle).
Mathematicians and math teachers love to celebrate pi Day by having parties, eating pie, and sometimes having pie fights according to some stories.
Mathematicians and math teachers also love our dry erase products because they help them do their jobs better. Solving math problems for students using the visual aid of a dry erase board makes it easier to comprehend for the whole class. Our Whiteboard In A Box product is perfect for expanding available space to teach. Our markers are also the best available, bold, bright, and long-lasting. And made in the U.S.A.
