Answer:
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
