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.
sector
The region bounded by an arc and two radii to the arc's endpoints is known as a sector of a circle. It resembles a "slice" of the circle, with the arc serving as the curved edge and the two radii as the straight edges extending from the center of the circle to the endpoints of the arc. The area of this sector can be calculated based on the angle subtended by the arc at the center and the radius of the circle.
A sector of a circle would fit the given description
It could be an arc (a curved portion of the circumference), a chord (the straight line distance between two points) , or a wedge (the plane area bounded by two radii and an arc).Remember the circle is a plane figure, not the curved line we draw. " A circle is bounded ... ."
Working in degrees, the angle of the greater radius, minus the lesser radius, all over 360, gives the proportion of the area of the circle that is bounded by the radii. This can then be multiplied by the area of the whole circle to give the bounded area.
A part of a circle (the area) bounded by an arc and a chord is termed a circular segment. A link can be found below.

The segment is called a secant.The area bounded by a secant and its arc is a sector.
An arc is part of the circumference of a circle and a chord is a straight line that meets two points of the circumference with the diameter being the largest chord.
