WebThe arc radius equation is a use of the intersecting chord theorem. In the figure on the right the two lines are chords of the circle, and the vertical one passes through the center, bisecting the other chord. The blue segment is the arc whose radius we are finding. Its width is 2a, and height b. Recall from the intersecting chord theorem that. WebWe will use the formula for arc length of a circle given an angle in radians: S = Rθ. We already know that R = 9 feet and θ = π/3, so we get: S = 9 (π/3) S = 3π. The arc length is 3π feet, or approximately 9.42 feet. Note that this arc length is 1/6 of the circumference, since C = 2πR = 2π (9) = 18π.
