Introduction on Properties of Circle
By learning, Circle consists of set of points from middle point. The point from the all points on a circle are equidistant is called the center of the circle, and the distance from that point to the circle is called the radius of the circle. illustration of circles is in single letter, its center. Circle has center point C and a radius of length r.

Properties of Circle:

Let we see about the properties of learning circles:

• The arc of a circle has two points on the circle and all of the points on the circle that lie between those two points.

• Chord is a segment and consists of end points which is on a circle.

• Diameter of circle:

Length of diameter = 2 × length of the radius.

• Circumference of a Circle:

Circumference = 3 × diameter (approx.).
These are the properties of learning circles.
Formulas of learning circles:
The area of circle:
Area of circle = 'pi' * r²
where, r is the radius of the circle.
The diameter of circle:
Diameter of circle = 2 * r.
where, r is radius of the circle.
The circumference of circle:
Circumference of circle = 2* 'pi' *r (or) 'pi' *d.
where,r is the radius of the circle.
d is the diameter of the circle.
