Question

find the length of an arc of a circle of radius 5cm subtending an angle of 15 degree at the centre​

Answer 1

Answer:

sorry I didn't understand

Answer 2

Let s be the length of the arc subtending an angle θR at the centre of a circle of radius r. Then, θ=s/r.

Here,    r=5 cm and θ=15∘=(15×180π)R=(12π)R

∴   θ=rs or 12π=5s or s=125π cm
