When graphing inequalities you use a circle to indicate a value on a graph. If the value is included in the solution to the inequality you would fill in the circle. If the value that the circle represents is not included in the solution you would leave the circle unshaded.
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.

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 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.
The boundary or perimeter of a circle is called the circumference. The formula for calculating the length of the circumference is C = 2πr.

Approximately 66° 33' 39" N marks the boundary of the Arctic Circle
Circumfrence
With an open circle, the number at which the circle is is NOT included in the dataset; with a closed circle it is. For example if a line is drawn on the number line between 0.5 and 1.5 with a closed circle at 0.5 and an open circle at 1.5, then it represents the numbers between 0.5 and 1.5 including 0.5 but excluding 1.5; this range is the numbers which round to 1 to the nearest whole number.
It is not necessary - it is a convention to distinguish between the end points of a range being included or not in the solution.

an open circle on a number line means the answer is just less than or greater than (< or >), but a closed circle means the answer is less than or equal to, or greater than or equal to (< or > with a line under it)
