    Circle

    Is it accurate to call a circle a loop? The circumference of a circle makes a loop, but a circle is everything inside, too. On edit: Apparently it is! I thought that pi r squared was the area of a circle, but according to Wikipedia it’s the area enclosed by a circle of radius r. TIL. (Or at least re-learned something I was taught oh so many years ago.)
