In mathematics, the circumference of any shape has been perfectly defined as the path or boundary that will help in surrounding that particular shape. In other words, the circumference is the synonym for the term perimeter which can be perfectly utilised in terms of identification of the length of the outline of any shape. It is very much important for the kids to be clear about the circumference of the circle in the form of definition, formula and methods so that they can make real-life accurate decisions.

The circumference of circle or perimeter of the circle can be very clearly known as the measurement of the boundary of the circle. On the other hand, the area of the circle will be defining the region occupied by it. Whenever people will be opening a circle and making a straight line out of it will be known as the circumference and it will be generally measured into units like centimetre or meter.

## The formula for the circumference of the circle has been explained as follows:

- It will be considered as two into the value of pi into the value of radius
- The value of pi over here can be considered as 3.14 or 22/7

One can also consider the circumference as the value of pi into the diameter of the circle

It is also very much important for the kids to be clear about the area of the circle formula which can be perfectly described as the value of pi into the square of radius in the whole process. Apart from the basic circle kids also need to be clear about the concept of the semicircle and the perimeter of semicircle has been explained as follows:

The perimeter of the semicircle will come out to be the value of pi into radius +2 into the radius

The area of the semicircle will always come out to be the half of the normal circle and the formula will be pi into the value of radius Square/2

It is very much important for the kids to be clear about the radius of the circle as well because this will be the distance from the centre to the outer line of the circle. This is considered to be one of the most important components of the circle because the different kinds of formulas will be based upon this concept only.

Twice the radius of the circle will be known as the diameter and it will be helpful in terms of cutting the circle into two parts which will be known as a semicircle. The basic meaning of circumference will be the distance around the circle or any other kind of shape. This will be the dimensional linear measurement of the boundary across the two-dimensional circular surface and it will also follow the same principle behind finding the perimeter of any other kind of polygon.

## There are two methods of finding out the circumference which is explained as follows:

- One cannot physically go with the option of finding out the circumference which is the main reason that people can depend upon utilisation of the thread in the whole process so that part of the circle can be traced and measurements can be undertaken With the help of a normal ruler.
- Another accurate way of measuring the circumference of the circle is to depend upon the formula implementation so that calculation can be very much accurate as well as easy.

Hence, being clear about the basic concept of diameter of circle and circumference of a circle is very much vital on the behalf of kids and for this depending upon Cuemath is a good idea because of the expertise and professionalism element provided by them.
