Question

The radius of a circle is 14 cm. The angle subtended by an arc of the circle at the centre is 45". Then the length of the arc is (app)1) 11 cm 2)10 cm 3)8 cm 4)16 cm​

Answer 1

Answer:

Given that,r=14cm and θ=45∘

∴θ=45∘=45×180π=4πc

Length of the arc=l=rθ=14×4π

=27π

=27×722=11cm

∴ Length of the arc is 11cm

Step-by-step explanation:

Given that,r=14cm and θ=45∘

∴θ=45∘=45×180π=4πc

Length of the arc=l=rθ=14×4π
