WebJan 22, 2013 · Assuming you are asking for the area of the circle which has a circumference of 40.8 cm: circumference = 2 x π x radius → radius = circumference/2π area = π x radius2 = π x (circumference/2π)2 = circumference2/4π = … 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.
