circumference,Circumference,"In geometry, the circumference (from Latin circumferens, meaning ""carrying around"") of a circle is the (linear) distance around it. That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment. Since a circle is the edge (boundary) of a disk, circumference is a special case of perimeter. The perimeter is the length around any closed figure and is the term used for most figures excepting the circle and some circular-like figures such as ellipses. Informally, ""circumference"" may also refer to the edge itself rather than to the length of the edge.",,Wikipedia,https://en.wikipedia.org/wiki/Circumference,Added to support Critical Zone Observatory (CZO) data use cases.
