added Category:Circles using HotCat
Slice of a circle enclosed between any two radii is called a sector.Semicircle and quadrant are special types of sectors.
=== Objectives ===
* To understand area enclosed by two radii is sector.
===Estimated Time===
*15 minutes
===Prerequisites/Instructions, prior preparations, if any===
* The students should know a circle, centre, radius,circumference and a sector.
* They should know that circle is a planar figure.
