centre, if the radius of the circle is 15
cm.​

Answer 1

its difficult dear

..sorry no time...

hmmmm

keep smiling

Answer 2

Answer:

The length of arc is 28.275 cm.

Given information: subtends angle at the center 108° and radius of the circle is 15 cm.

Formula for length of arc is

$l=r\theta \:$

where, r is radius of the circle and θ is the subtends angle at the center.

$\theta=108\times \frac{\pi}{180}radian=1.885radian \:$

The length of acr is

l=15\times 1.885

l=28.275

Therefore the length of arc is 28.275 cm.

hope this helps you
