The circumference of a circle refers to the total distance around its outermost boundary. This can be computed by applying the formula C=2πr, where 'r' represents the radius of the circle. Alternatively, one can use the formula C=πd, where 'd' denotes the diameter of the circle. Each of these formulas incorporates π (pi), an essential mathematical constant which is roughly equivalent to 3.14.
