The boundary which defines the area of a circle is known as the circumference of the circle.However if one wants to be precise, the circumference is the distance around the outside of the circle, not the circle itself. The term "circle" itself means the boundary. It has an interior and an exterior.A circle can be defined as all the points that are the same distance from a given point.
That sounds like the northern border of Delaware.
It is a round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center).
In everyday use, the term "circle" may be used interchangeably to refer to either the boundary of the figure (known as theperimeter) or to the whole figure including its interior. However, in strict technical usage, "circle" refers to the perimeter while the interior of the circle is called a disk. The circumference of a circle is the perimeter of the circle (especially when referring to its length)
The distance around a circle is called circumference. Around any other shape, it is called perimeter.
The boundary or perimeter of a circle is its circumference.
The diameter of a circle is a straight line going from one point on its boundary, through the centre of the circle, to the boundary on the other side.
Delaware has a boundary that is a curve (part of a circle). The arc radius is 12 miles. By default, the adjoining State of Pennsylvania also has a curved boundary.
Approximately 66° 33' 39" N marks the boundary of the Arctic Circle

its called a Radius
The Antarctic Circle
Not at all! The circumference is the length of the boundary of a circle. A chord is a straight line(or a line segment) that passes through two points on the boundary of a circle (or on a curve).
It is an "open" circle. That is, a circle which is not filled in.
The radius of a circle is a line segment joining any point of the boundary of the circle to its centre. A diameter is a line segment from a point of the boundary of the circle which passes through the centre and ends at the boundary on the opposite side.

If it is a sector of a circle then the arc is the curved part of the circle which forms a boundary of the sector.
