### What Is Circle?

It is not much dificult to remember formulas for calculating Circle Area, Diameter and Circumference/ Perimeter if any one value is provided. We just want to make it easy to calculate through this calculator.

### What Are Calculation Option Available in Circle?

Select which value you are providing (Area, Diameter, Circumference), input value and click on Compute!

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

Diameter :

D = 2r
Where
D = Diameter

Circumference :

C = 2πr
Where
C = Circumference
