Since the central binomial coefficients are related to Catalan numbers, Wallis' product \( \pi \) approximation for each \( n \) is inversely proportional to the number of ways a regular \( n \)gon can be divided into \( n2 \) triangles. As \( n \rightarrow \infty \) then the \(n\)gon shape approaches a circle. Wait, \( \pi \) is related to circles because of triangles? 17bii  32s  32sii  41c  41cv  41cx  42s  48g  48g+  48gx  50g  30b
