WebArea of a 4′ diameter circle (results may be rounded) Area of a Circle Formula The area of a circle is pi times the square of its radius. The radius is half the diameter. Area = π * (Diameter / 2)2 Diameter of a Circle The diameter of a circle is the distance from one edge to the other, passing through the center. It is twice the radius. Diameter
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.
