If you squint hard enough, the capital letter pi (Π) looks like half a circle.

Maybe this is why pi was chosen for half of the circumference of a circle.

I can level up with more sources (stanford, wiki).

The circumference is 2pi x radius, which obviously means half the circumference is pi x radius.

Edit: formatting. Asterisk results in italics
