#### Making Sense of the Circle Area Formula (TPU Flexible Filament)
**Update** At the suggestion of some users, I added a 12-piece dissection of the circle, where each wedge is 30 degrees. It is now possible to make 30, 60, 90-degree angles.
Circles are the most universal shapes in nature, design, and, of course, school mathematics across P-12 and beyond! Frequently, we have students who would say π (PI) is 3.14 and the area of a circle is πR^2, struggling to explain why? In
