Circumference with radius
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. WebDec 14, 2024 · To find the radius of a circle with a circumference of 10 centimeters, you have to do the following: Divide the circumference by π, or 3.14 for an estimation.
