Question

A circle of 120 m is divided into 8 equal sectors. Find the length of the arc of each of the sectors.

Answer 1

Answer:

length=94.25m

EXPLAINATION:

# 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.
