The segment is called a secant.
The area bounded by a secant and its arc is a sector.

The correct term for a line segment with both endpoints on a circle is a chord. The diameter of a circle is also a chord.
chord
A chord is a line segment whose endpoints lie on a circle. A secant is a line (or line segment) that intersects a circle in two places, endpoints NOT on the circle.
A diameter is a segment that passes through the center of a circle and has both endpoints on the circle.

A chord
The region bounded by an arc and a chord is known as a "segment" of a circle. This segment includes the area enclosed by the chord and the arc connecting the endpoints of the chord. The segment can vary in size depending on the length of the chord and the curvature of the arc. If the chord is a diameter, the segment is known as a semicircle.
This segment would be the radius of a circle.
An arc is a part of a circle that is defined by its endpoints. It is a segment of the circumference of the circle.
The correct term for a line segment with both endpoints on a circle is a chord. The diameter of a circle is also a chord.
