Question

the radius of a circle is 14cm. the angle distended by an arc of the circle at the centre is 45. then the length of arc is

Answer 1

Hi ,

Radius of the circle ( r ) = 14cm

Angle subtended by an

arc at the center = x° = 45°

Let the length of the arc = l cm

l = ( x / 360 ) × 2πr

= ( 45/360 ) × 2 × ( 22/7 ) × 14

= 11

Therefore ,

Length of the arc = l = 11 cm

I hope this helps you.

Answer 2

the radius is 14cm 
angle 45
then by equation to find length of arc

we get 11 cm is the answer...
