Question

in circle O, central angle AOB measures radians. What is the length of arc AB? 6π cm 12π cm 18π cm 36π cm

Answer 1

The answer is 6 pi because you have to divide 18 by 3.  That gives you 6.

Answer 2

The length of the arc is 6π cm.

Given that

In circle O, central angle AOB measures π/3 radians and radius is 8cm.

We have to determine

What is the length of arc AB?

According to the question

The length of the arc is determined by the following formula;

$\rm Length \ of \ the \ arc = Central \ angle \times Radius$

In circle O, central angle AOB measures π/3 radians and radius is 8cm.

Then,

The length of the arc is

$\rm Length \ of \ the \ arc = Central \ angle \times Radius\\\\Length \ of \ the \ arc = \dfrac{\pi }{3} \times 18\\\\Length \ of \ the \ arc = 6\pi$

Hence, the length of the arc is 6π cm.
