A circle is one of its kind among all the geometrical shapes; it is the only shape where all points are equidistant from a given point called the Center. Thus a circle is formally defined as:

A circle is a closed plane consisting of all points which are equidistant from a fixed point called as Center. Note that, a circle:

Note: The radius of a circle is generally represented by the letter ‘r’. A circle refers to only the outer boundary whereas a disc refers to the whole shape including the inside part. Since the circle is curved and doesn’t contain any line segments surfaces, it doesn’t come under the family of the polygon

How to use CalculatorHut’s Circle Area Calculator?

We know that the area a circle is ’π’ times the radius squared of the circle and the circumference is two times the product of ’π’ and ’r’ . All we need is to find the radius of the circle. Since π is an irrational value, it is challenging to calculate the area and circumference of the circle and is a time taking process. Even if there is a small calculation that goes wrong the entire value chance.

To avoid all this, it is better to go with this Circle Area Calculator as one we get accurate results in seconds. Even by adjusting the units of the circle you can perform in different units and get whatever result you need. This not only saves your time but also helps you to complete your task with greater accuracy.
