The sector of a circle is a partition of that circle. A sector extends from the center, or origin, of the circle to its circumference and encompasses the area of any given angle that also originates from the center of the circle. A sector is best thought of as a piece of pie, and ...
A chord of a circle that has the center in it is referred to as the diameterof a circle. Diameter is the largest chord of a circle that passes through the center of the circle. There is a circle with \(O\) as a centre and \(OP\) as a radius. In the figure, you can see the...
