Question

Find the length of an arc of a circle with a 8-cm radius associated with a central angle of 240 degrees. Give your answer in exact and approximate form to the nearest hundredth.

Answer 1

Answer:

l = 1920 cm

Step-by-step explanation:

Given that,

The radius of circle, r = 8 cm

The central angle is 240 degrees

We need to find the length of the arc. We know that,

$l=r\theta$

Where

l is the length of the arc

So,

$l=8\times 240$

$\implies l=1920\ cm$

so, the length of the arc is equal to 1920 cm.
