The formula used to calculate the circumference of a cylinder is obtained by multiplying the radius by 2 to obtain the diameter and then multiplying the result with pie (π) = 3.141. Thus, the formula to calculate the circumference of a cylinder is given below: Circumference (C) = 2πr, here π = 22/7 = 3.141, r = radius. WebThe ratio of the length (circumference) of a circle, C to its diameter m is π (a Greek letter spelled pi and pronounced "pie" in English-speaking countries). The decimal representation of π continues forever without repeating after the decimal point: π = 3.14159265... So if C / m = π, then C = m ⋅ π.
