What Happens If You Keep Splitting A Half Circle 🤔

If you draw a half circle with a radius of one, the curved edge will measure pi. Now, if you split that curve into two smaller half circles, their curves will still add up to pi. Then, split them again and again, making more and more tiny curves. Eventually, the shape starts to look flat, like a straight line that's twice as long as the radius. But, the curves never actually become straight cuz even when they get extremely small, those pieces are still curves that always add up to pi.
