A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted, clever little truths, hidden in daily life.

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

That's not half the circumference then is it???
Now you're just being silly.
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.
