How to Find Circumference of Circle?

Perimeter of a circle is found using any of the two approach added below,

Approach 1: Due to its curved nature, directly measuring the length of a circle with a ruler or scale isn’t feasible as it is for polygons like squares, triangles, and rectangles. However, you can determine the circumference of a circle using a thread. By tracing the circle’s path with the thread and marking points along it, you can measure this length using a standard ruler.

Approach 2: A precise method to ascertain a circle’s circumference involves calculation. To do this, the circle’s radius must be known. The radius of a circle is the distance from its center to any point on its circumference. In the illustration below, a circle with radius R and center O is depicted. The diameter, twice the radius of the circle, is also shown.How to Find the Circumference of a Circle?
