Region enclosed by a circle a convex set?

convex
Is a circle a convex set?
no
What is the part of the circle enclosed by two radii?
A part of a circle enclosed by two radii is called a sector.
What part of the circle is The area of a circle enclosed by 2 radii and an arc?
It is a sector of the circle
Area enclosed within the central angle of a circle and the circle?
Area of a sector of a circle.
What is a major sector of a circle?
A sector of a circle is the region enclosed by two radii and the circumference. If you draw a picture, you can see that there are actually two regions formed. One has an angle of 180 degrees or less at the center, and the other has an angle of 180 degrees or more. A sector which occupies more than half of the circle is a major sector. To put it more succinctly, a major sector is enclosed by two radii and a major arc of a circle.
What are segments of a circle called?
Exactly as in the question and a segment of a circle is the area enclosed by a chord and an arc of a circle.
What type of polygon is found in a geometry circle?

What is the area enclosed by a chord of a circle?
The area enclosed by a chord is equal to the area enclosed by a segment minus the area enclosed by the triangle with the same corners as the segment. To visualise it, draw a circle and put a chord on it. Label the chord AB and the centre of the circle C. The area of sector AB equal to the area of sector ABC minus the area of triangle ABC.
