網頁2016年12月26日 · Explanation: The area of a circle can be obtained by using the equation below: where the mathematical constant, π, has a value of approximately 3.14 and r represents the radius of the circle. All we have to do is square the given radius and multiply that value by π to figure out the area: Area = (3cm)2 ×π. Area = 28.27cm2. 網頁The 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.
