4.24 Circle Facts
Circle is the set of all points in a plane at a fixed distance, called the
radius
, from a given point, the
centre
.
A circle can be drawn with the help of a
compass
.
A line from the center to any point on the circle is called
radius
.
The distance across a circle through its center is called its
diameter
.
Diameter is twice the radius.
A line segment joining two points on a circle shown in the figure is called a
chord
.
DC is the chord
SC is the diameter
PC is the radius
P is the center
Diameter is the biggest chord and divides the circle into exactly two halves.
The circumference of a circle is the perimeter of the circle.
The distance around a circle is called its
circumference
.
The formula to find the circumference of the circle is C = Pi x 2 x r
The area of the circle is A = Pi x r
