Calculation of the Circumference of a Circle

To find the circumference (C) of a circle with a radius (r) of 2 meters, we can use the formula C = 2πr, where π is a mathematical constant approximately equal to 3.14.

Substituting the given radius value into the formula, we have:

C = 2π(2) = 4π meters.

Therefore, the circumference of the circle is 4π meters.

Note: The value of π is approximately 3.14, but it is an irrational number that extends infinitely without repeating decimals.
