Length of arc AD = 15.7 cm

Step-by-step explanation:

Length of arc =

Here, θ = Central angle subtended by the arc

r = radius of the circle

From the picture attached,

Central angle subtended by arc AD = 360° - (180° + 66.4°)

                                                            = 113.6°

Length of arc AD =

                             =

                             = 15.655 cm

                             ≈ 15.7 cm

Length of arc AD = 15.7 cm
