No. A sector is bounded by part two radii and part of the circumference.
sector
The region bounded by an arc of a circle and the radii to its endpoints is known as a sector. A sector resembles a "slice" of the circle and is defined by the two radii extending from the center of the circle to the endpoints of the arc. The area of this sector can be calculated based on the central angle and the radius of the circle.

Central Angle An angle in a circle with vertex at the circle's center.
The central angle is the angle that has its vertex at the center of the circle.
Radius: A line from the center of a circle to a point on the circle. Central Angle: The angle subtended at the center of a circle by two given points on the circle.
Central Angle
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.
An angle that's vertex is on the center of the circle.
