Circumference (from Latin circumferentia, meaning "to carry around") is the linear distance around the edge of a closed curve or circular object.[1] The circumference of a circle is of special importance in geometry and trigonometry. However "circumference" may also refer to the edge of elliptical closed curve. Circumference is a special case of perimeter in that the perimeter is typically around a polygon while circumference is around a closed curve.
