In the world of geometry, different kinds of shapes can be categorised into 2-D shapes and 3-D shapes. The two-dimensional shapes as the name suggests will be only having two dimensions which will be length and breadth and on the other hand, three-dimensional shapes will be having three dimensions which will be the length, breadth as well as height. All these kinds of shapes are perfectly defined with the help of different terms and one such great parameter which is very much capable of defining the shape of the circle is known as the diameter of circle.

The circle is a two-dimensional shape where the collection of points on a particular surface of the circle will be equidistant from the centre point. The distance from the centre to any kind of point on the surface will be referred to as radius and similarly the distance from one point to the surface of the other one through the centre will be known as the diameter of the circle. In other words, the diameter of the circle will be twice the radius and one can very easily say that the diameter of a circle will be the longest chord of the circle. The formula for the diameter will be in the terms of radius only and has been explained as follows:

- D is equal to 2 into R

If the circumference of the circle is well-known then the formula to calculate the diameter will be:

- D is equal to C/ The value of pi.

In the above-mentioned formula, C has been described as the circumference of the circle and pi will be the constant value which will be directly linked with the value of 3.14. If the area of the circle is known to the people then the formula of diameter will differ and has been explained as follows:

- In this particular case, the diameter will be equal to the square root of the area upon the value of pi.

## Following are the most important properties of the diameter of a circle:

- The diameter of the circle is considered to be the longest possible chord in any of the circles without any kind of problem.
- The diameter of the circle will always help in dividing the circle into two equal parts and will always help in producing the two equal semicircles.
- The midpoint of the diameter will be the centre of the circle
- The radius should be half of the diameter always and vice versa

It is very much important for the kids to remember the formula of the diameter of the circle so that they can solve the questions very easily and the best possible way of remembering this particular formula is to divide the circumference by the value of pi which will help in providing the people with right kind of accurate answers without any kind of problem. Also being clear about different kinds of properties of the diameter in terms of twice the radius is very important so that overall goals of solving the questions are accurately or significantly achieved and there is no hassle to the kids at any point in time. Apart from this being clear about the formulas associated with the circumference of circle and the area of the circle is another very important thing to be undertaken by the students so that they can clear all the doubts in their minds and unable to perform well in the examinations.

Apart from this being registered on the platforms like Cuemath is a wonderful idea on the behalf of people so that they can get rid of the confusion element very easily and there is no hassle throughout the process which will further make sure that people will become masters of this particular subject and will be able to score well in the exams.
