How to work out circumference of circle
WebCircumference of circle = 2 × π × radius Again, as stated above, you can find π in your calculator and its numeral value is approximately equal to 3.14. Because the radius is just half of the diameter. The formula for calculating the circumference using the radius is fairly similar to C = πd. 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. Share Cite Follow answered Apr 1, 2016 at 21:58
