WebThe circumference can be found by the formula C = πd when we know the diameter and C = 2πr when we know the radius, as we do here. Plugging our radius of 3 into the formula, we get C = 6π meters or approximately 18.8495559 m. Now we multiply that by (or its decimal equivalent 0.2) to find our arc length, which is 3.769911 meters. WebJan 11, 2024 · The arc length is the fractional amount of the circumference of the circle. The circumference of any circle is found with 2\pi r 2πr where r = radius. If you have the diameter, you can also use \pi d πd where d = diameter. The formula for finding arc length is: Arc length= (\frac {arc angle} {360°}) (2\pi r) Arclength = ( 360°arcangle)(2πr) fox bookcase
