WebFind the length of an arc whose radius is 10 cm and the angle subtended is 0.349 radians. Solution. Arc length = r θ = 0.349 x 10 = 3.49 cm. Example 6. Find the length of an arc in radians with a radius of 10 m and an angle of 2.356 radians. Solution. Arc length = r θ = 10 m x 2.356 = 23.56 m. Example 7 WebSo if we call the arc length S that gives us S/ (2pir) = 2/2pi. In english that says the ratio of the arc length S to the full circumference, 2pir is equal to the ratio of the angle of the arc length, 2 radians, over the full angle of the circle, 2pi radians. This would also work for degrees. Anyway, solving it for S gets you 2r like in the video.
