Pi Day is celebrated on March 14th (3/14 in the month/day
format) because the date represents the first three digits of π (pi), which is
approximately 3.14. Pi is a mathematical constant that represents the ratio of
a circle's circumference to its diameter. This ratio is constant for all
circles of any size, making pi a fundamental aspect of many mathematical,
engineering, and scientific calculations. Here are some of the useful uses of pi:
1. **Circumference and Area Calculations**: Pi is used to
calculate the circumference (C = 2πr) and the area (A = πr^2) of a circle,
where r is the radius of the circle. These formulas are foundational in
geometry and are widely used in various fields such as construction,
manufacturing, and design.
