WebYou can calculate the length of an arc by using the formula given below. Arc length of a circle = y 360 2 π r Where r = the radius of the circle y = the angle (in degrees) subtended by an arc at the center of the circle 360 = the angle of one complete rotation. The value of π (pi) = 3.14 Solved Examples WebFeb 2, 2024 · Recall the formula for the radius of a circle from circumference: r = c / (2 * π). Inject the circumference into the equation: r = (6 ft) / (2 * π) = 3/π ft. If needed, substitute π ≈ 3.14: r = 3/π ft ≈ 0.96 ft.
