What are Circle Formulas?

Circle formulae are important tools in geometry for computing the characteristics of circles. Let’s look at some typical circle formulae and see how they might assist us locate various parameters.

Diameter:(D) The diameter of a circle is the distance across it that passes through its centre. You may calculate the diameter by doubling the radius (r).

D = 2r

Circumference(C): The circumference of a circle is the distance around its outside edge. It is determined by multiplying the radius (r) by two times the mathematical constant π (pi).

C = 2πr

Area (A): The area of a circle is the space included inside its edge. It is calculated by squaring the radius (r) and multiplied by the constant π (pi).

A = πr2

In these formula, “r” stands for the circle’s radius. We may use these formulae to discover distinct characteristics of circles, which will be useful in a variety of real-world applications and mathematical computations.

Circle Formulas For Diameter, Area and Circumference

Circle formulas are basic formulas used in geometry to solve various problems of circles and are used in solving various mathematical and other problems. Before moving with various circle formulas one must familiarise with the basic definition of a circle. “A circle is a basic geometrical shape in which all points on the circumference of the circle are equidistant from the centre of the circle.”

In this article, we will learn about various circle formulas their uses and others in detail.
