Answer 1

Answer:

length of arc theta/360° into 2πr

45°/360°× 2×22/7×14

1/8×2×22×2

=11 cm

hope it helps u

Answer 2

The length of the arc is 11 cm .

Explanation:

The formula for length of arc is given by :-

$l=\dfrac{\theta}{360^{\circ}}\times2\pi r$

, where $\theta$ = Central angle.

r= radius of circle.

As per given ,

$\theta=45^{\circ}$

r= 14 cm

Substitute all the value in the formula , we get

$l=\dfrac{45}{360}\times2(\dfrac{22}{7}) (14)\\\\ l=11\ cm$

Hence, the length of the arc is 11 cm.
