Because the circumference of any circle divided by its diameter is equal to the value of pi which is an irrational number.
Because the circumference of a circle divided by its diameter is equal to pi.
Although it is different for pretty much each shape, the basic answer is just that you add up the sides. For circular shapes the formula is: Pi X Radius to the 2nd power
assuming the island is circular.... use the formula Area=(pi)x(radius squared) to find the radius, then use the formula C=2(pi)(radius) to determine the circumference.
the other formulas involve non-circular shapes

In mathematics, circumference refers to the distance around the boundary of a circle. It can be calculated using the formula ( C = 2\pi r ) or ( C = \pi d ), where ( r ) is the radius, ( d ) is the diameter, and ( \pi ) (pi) is a constant approximately equal to 3.14159. The concept is essential in geometry and is used in various applications involving circular shapes.
