It is an "open" circle. That is, a circle which is not filled in.
a circle?
If something says "greater than" or "less than" some function, then you will have a dotted or dashed line. The appropriate side of the line is shaded or hashed. If it says "greater than or equal" or "less than or equal", then you use a solid line. Then shade the appropriate side.
You substitute the coordinates of the point in the equation. If the result is true then the point is a solution and if it is false it is not a solution.
None can. A tangent is a line that touches a circle at only one point. If it wentthrough a point inside the circle, then it would have to touch the circle at twopoints ... one on the way in and another one on the way out.

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.
its called a Radius
The diameter of a circle is a straight line going from one point on the circumference (the boundary) of the circle, through the centre of the circle, to another point on the circumference.
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.
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.
An open circle is usually found on a number line in math. An open circle usually represents a number that is not included in the line.
It is a round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center).
Technically there are an infinite number of radii in a circle. A radius is a line from the center of the circle to a point on its edge, and since there are an infinite number of points on a circle's edge there are an infinite number of radii.

The curved line that traces the boundary or perimeter of a circle is called the circumference. A straight line that touches the circle at just one point is called a tangent. See the related link, 'The Parts of the Circle', below this answer.
