Only one endpoint? if two, it's a diameter...
Such a line segment would be a radius of the circle.
radius
The radius goes from the center out to the edge of the circle.
Is called a radius.
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.
The segment you describe is the radius of the circle.

A radius.
Is called a radius.
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 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.
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.
