🟣 CIRCLES 🟠
My Favorite Shape: Circle
February 9, 2026
Pi (π) is a mathematical constant representing the ratio of a circle's circumference to its diameter (c/d), which is about 3.14159. And the fact that it's an irrational number that continues infinitely without repeating is actually pretty amazing imo. 🔵 Btw, the Greek letter π is also used in other fields, too, including physics and engineering. I like circles because they're fun to measure and this number is not set , so it goes on forever and ever with no end.
How far have you memorized Pi (π)?
