how find circle area circumference diameter and radius step by step
Introduction:-
A circle is a collection of points placed at fixed distance from a fixed point on a plane.
The fixed point is called center and the fixed distance is called radius.
Radius of the circle:-
The line segment joining the center and any point on the circle is called circle.
The three divisions of circle:-
A circle divides the plane on which it is made into three parts.
They are :-
i) interior of the circle
ii) circle itself
iii) exterior of the circle
Chord of the circle:-
The line segment joining the two points distinct point on circle is called chord.
The chord which passes through the center is called the diameter of the circle.
Arc of the circle:-
A piece of circle between two points is called an arc .The longer piece is called major arc and the smaller one is called minor arc.
The complete length of the circle is called circumference.
Segment of the circle:-
The region between a chord and either of the arc is called a segment of the circle.
There are two types of the segment major segment and minor segment.
Sector of the circle :-
The region between an arc and the two radii , joining the center to the end point of the point of the circle is called a sector.same as segment there are major and minor sector.
diameter of circle = 2r
circumference = 2πr
area of circle = πr^2
r = radius of circle
π = consent value 3.14 OR 22/7
