Answer 1

The arc length of AB = 8.37 meters

Solution:

Degree of AB (θ) = 60°

Radius of the circle = 8 m

Let us find the arc length of AB.

Arc length formula:

`$\text { Arc length }=2 \pi r\left((\theta)/(360^(\circ))\right)`

`$=2 * 3.14 * 8\left((60^(\circ))/(360^(\circ))\right)`

`$=2 * 3.14 * 8\left((1)/(6)\right)`

`$=2 * 3.14 * 4\left((1)/(3)\right)`

Arc length = 8.37 m

Hence the arc length of AB is 8.37 meters.
