Area of Sectors

Videos, worksheets, games and acivities to help Geometry students learn how to find the area of sectors.

 

 

Area of a Sector
A sector in a circle is the region bound by two radii and the circle. Since it is a fractional part of the circle, the area of any sector is found by multiplying the area of the circle, pi*r^2, by the fraction x/360, where x is the measure of the central angle formed by the two radii.
