this line is a radius

the diameter is the half of radius

sector is a and b

Answer 2

Answer with explanation :

Center of a circle (O) : It is a point which is equidistant from all the points of the circle.

Radius (OP, OB, OA) : It is the line segment between the center and the arc of the circle.  

Diameter (AB) :The chord passing through the center is called diameter.

Sector (Green Region): The region between an arc and two radii is called sector.

Segment (Pink region): The region between an arc and a chord is called segment.

Arc ($\overarc{BP}$) : It is the length of two points on a curve.

Interior point (X): The point which lies interior of circle. X is an interior point.

Exterior point (Y): The point lies outside the circle is called exterior point. Y is an exterior point.
