circumferences

Distances around closed curves

Circumferences is the plural of circumference, the distance around a circle or curved shape—essentially its perimeter.

The term extends to any boundary line enclosing an area: The circumferences of the two lakes differ by several miles.

In technical contexts, comparing circumferences helps calculate proportions or fit: The circumferences of these pipes don't match.
