Question

what is the length of arc of a circle of radius 30 cm which subtend an angle of π/6 at the centre​

Answer 1

Answer:

900 cm is the answer.

we know that [ S = Rθ where R = radius and S = length of the arc and θ = measurement of the angle in radian ]

s=30×π/6

=30×180/6

= 900 cm

Answer 2

Answer:

Length of arc = Radius × theta

L= 30 cm × pi/ 6

L = 5× pi cm

L = 15.7 cm

= 0.157 m
