Question

In the adjoining figure find the length of an arc AxB in terms of r and Tita

Answer 1

Answer:

Rθ  if θ is in radian

Rθ(π/180) if θ is in degree

Step-by-step explanation:

In the adjoining figure find the length of an arc AxB in terms of r and Tita

Arc AB shown in green color

length of arc AB = (θ/360) 2 π R  = Rθ(π/180)

if θ is in radian than 360° = 2π

then length of arc = (θ/2π)2 π R = Rθ
