WebMay 18, 2024 · Divide by 360 to find the arc length for one degree: 1 degree corresponds to an arc length 2π R /360. To find the arc length for an angle θ, multiply the result above by θ: 1 x θ = θ corresponds to an arc length (2πR/360) x θ. So arc length s for an angle θ is: s = (2π R /360) x θ = π Rθ /180. too young sabrina carpenter lyrics
