Parts of a Circle

Parts of a Circle:Let us now learn about Parts of a Circle.The circle is symbolically represented as Circle . The circle can drawn by at a point rotate with one complete revolution as 360° without changing the radius. That point which used for make the circle is called as the center of the circle. Let us about the parts of the circle and how to calculate that parts.Radius-It is the parts of the circle that be defined as the distance between the center of the cirlce and a point on the circle. It is denoted as the r.Diameter:Let us see what we understand about diameter of a circle,it is the parts of the circle that be defined as the distance between the two point on the circle which cross through the center of the circle. Its symbol is d. It is also called the longest chord, but not a every chord is a diameter.The diameter is twice the times of radius in the circle.Formula: D = 2r or r =(½) d.Chord-It is the parts of the circle that be defined as the line whose end points are on the circle.Secant Line: It is defined as the line that be intersect the circle exactly at two points.Tangent Line-It is defined as the line that be intersecting the circle on the point.Hope you like the above example of Parts of a Circle.Please leave your comments, if you have any doubts.
