As you know from reading my previous blogs (The Hidden Structure of 1/7 and Exploring Consecutive Squares with 9/16/25), I am a big fan of combining math with dates. This week allowed us to celebrate another math date! Pi Day (March 14th) was just this past weekend, so it felt like the perfect time to highlight a formula hiding in plain sight.
Most of you know that Pi is rounded to 3.14 and that the value is used for various calculations associated with a circle. But did you know that Excel has a function associated with Pi?
The =PI() formula returns Pi accurate to 15 digits. It only goes 15 digits deep due to how Excel handles floating-point arithmetic (Excel converts anything larger than 15 digits into scientific notation).

We all know that MATH IS AWESOME, but Math times Pi makes it three times more awesome!
