Circle

r=Radius
d=Diameter
A=Area
C=Circumference


 

A circle can be defined as a shape in which all points on the shape are an equal distance from a central point. The circumference of a circle is the measure of how far around the edge of the circle is. It can be calculated by multiplying pi (3.14159265358979323846) by the diameter or 2 times pi times the radius. The area of a circle is found by multiplying pi (3.14159265358979323846) by square-root(radius squared). We can find all the properties of circle By using following formula :

Area :

A = πr2
Where
A = Area
r = Radius

Diameter :

D = 2r
Where
D = Diameter
r = Radius

Circumference :

C = 2πr
Where
C = Circumference
r = Radius
