Question

the angle of sector if a circle is 108 degrees and radius of the circle is 15 cm. the ratio of the circumference of the circle and length of the arc of the sector is?

Answer 1

Answer:

The length of arc is 28.275 cm.

O = 108 x π/180 radian = 1.885 radian

Step-by-step explanation:

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

Formula for length of arc is

l = rO

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

O = 108 x π/180 radian = 1.885 radian

The length of acr is

l = 15 x 1.885

l = 28.275

Therefore the length of arc is 28.275 cm.
