The answer depends on where the other end of the line segment is. If it is on the circumference the segment is a radius. Otherwise, it is indeterminate.
Its the radius

The equator is an imaginary circular line around the entire earth, with the center of the circleat the center of the earth.Any circle that has its center at the center of the earth divides the earth's surface exactly in half.
Technically, in geometry, there is no such thing. By definition, a line is infinite. A "line segment" is a finite portion of a line. In everyday speech, people might sometimes refer to a line segment as a finite line. But if you said this on a math test, you would fail the test.
Paired lines of longitude (a line and its partner 180 degrees of longitude away) are great circles. A great circle is a circumference of the planet, whereas a small circle is a circular path (slice of a sphere) that does not circumscribe the sphere.

There are 2,000 metres in a circle where the circumference (length around it) is 2km. There are 6,283 metres in the circle circumference (c) where the diameter (d - straight line that passes through the centre and whose endpoints are on the circle) is 2km. Using the formula c = Pi * d. Pi = 3.1415 There are 12,566 metres in a circle circumference (c) where the radius (r - line segment from the centre of a circle to the perimeter) is 2km. Using the formula c = pi * 2r. Pi = 3.1415. There are 12,566,00 m^2 in a circle with a radius of 2km. Using the formula area = pi * (r)^2
Such a line segment would be a radius of the circle.
The line segment is a radius.
The segment you describe is the radius of the circle.
diameter
radius
The radius goes from the center out to the edge of the circle.
A line segment with the center of a circle as one endpoint and the other endpoint on the circumference of the circle is a rdius of that circle.
A radius.
Only one endpoint? if two, it's a diameter...
If it connects the center of the circle to the edge, it is the radius. If it is a straight line that connects the edges of a circle through the center, it is the diameter.
A radius of a circle is a line segment joining the center of the circle to a point on the circle. All such segments have the same length, and this length also called the radius of the circle.
A line segment drawn through the centre of a circle and having endpoints on the circumference of that circle is called the diameter. Notably, a line segement with one endpoint at the centre of the circle and one anywhere on the circumference of the circle is called the radius, and is exactly half the length of the diameter.
