Sector Area and Segment Area

Sector of a Circle:

-A sector of a circle is a area bound by two radii of a circle and their intercepted arc.

Area:

-To find the area of a sector, use the following equation:

Segment of a Circle:

-A segment of a circle is an area bound by an arc with its chord.

To find the area of a segment, first:

1. Find the area of the sector.

2. Find the area of the triangle: A=1/2bh

3. Find the difference between the area of a sector and the area of a triangle.

4. This is the area of a segment.
