How do you determine the length of an arc
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 … WebCircumference of a circle. See video transcript. We usually measure length with a straight line, but curves have length too. A familiar example is the circumference of a circle, which has length 2\pi r 2πr for radius r r. In general, the length of a curve is called the arc length.
