Question

A circle of radius 12cm is divided into 8 equal sector.find the length of the arc of each of the sector.​

Answer 1

Answer:

Given -

r = 120 m

# Solution -

Circumference of the circle is calculated as -

c = 2πr

c = 2 × 3.142 × 120

c = 754 m

As the circle is divided into 8 equal sectors, each sector will have length equal to 1/8th of circumference.

l = c/8

l = 754/8

l = 94.25 m

Therefore, length of arc of each sector is 94.25 cm.

Answer 2

Answer:

9.42 cm

Step-by-step explanation:

radius = 12cm

circumference = 2πr

= 2*3.14*12

= 75.36

75.36 / 8

=  9.42 cm
