what's the Radius of a Circle?

You all can be acquainted with a circle, a well-known and widely used geometrical parent.

“The space from the center of a circle to any of its points at the circumference is referred to as the radius”  

The way to locate the Radius of a Circle?

In geometry, a circle is described by means of many related entities. And if you are willing to discover its radius given exclusive parameters, then these include:

Radius of a Circle components:

From Diameter:

As we know that:

\(Diameter=D=2*r\)

or

\(r=\dfrac{D}{2}\)

From Area:

You know that:

\(Area=A=?r^{2}\)

or

\(r^{2}=\dfrac{A}{?}\)

From Circumference:

As you know that:

\(C=2*?*r\)

or

\(r=\dfrac{C}{2?}\)

From area and critical attitude of a area:

You know that:

\(A=\dfrac{\theta}{360^\text{o}}*?*r^{2}\)

or

\(r=sqrt{\dfrac{A*360^\text{o}}{\theta*?}}\)

Example:

Let us resolve an example that could help you in locating the radius of a circle:

Statement:

What’s the radius of a circle having area as \(113m^{2}\)?

Solution:

\(r^{2}=\dfrac{A}{\pi}\)

\(r^{2}=\dfrac{113}{3.14}\)

\(r^{2}=35.986\)

\(r=\sqrt{35.986}\)

\(r=5.999\)
