Question

an arc of a circle of radius 15 cm subtends an angle of 160° at the centre of the circle find the length of the Arc pq take pie is equals to 3.142​

Answer 1

Answer:

160÷360×2×22/7×15 than you get answer

Answer 2

⇒Length of an arc= 15cm

⇒ θ = 45degree

Length of an arc =     θ  

                                 360

⇒ θ is angle subtended at a center.

            2πr is circumference of a circle.

∴  15=  45        (2πr)

            360

∴  r = 15*4 = 60
