etc. This is used to find out all the parameters involved in the circle with the help of formulas and especially

the properties of the circle. This is very useful tool as it can be used in different areas. It can be used to

calculate the fencing area application. One can determine its worth by just understanding its concepts. Early

prediction of fencing etc helps in saving cost also. So it has overall valuable application in many of the fields.

Two of the examples are shown below which can be useful in understanding purpose.

To find the radius of circle:

We know that, Circumference of the circle is 2 * pie* r

Therefore, 2* pie*r = 44

To find the radius of circle:

We know that, Circumference of the circle is 2 * pie* r

Therefore, 2* pie*r = 88

Hence radius of circle = 44/ 2* pie = 88 / 2* 22/7 = 44*7/22 = 2 *7 = 14cm
