Question

Find the length of the arc to 2 decimals places

Answer 1

Explanation:

The formula for arc length is

`AL=(\theta)/(360)*2\pi r` where theta is the measure of the central angle and r is the radius. We have both of those pieces of info; filling in:

`AL=(30)/(360)*2(3.14) (4)` and simplifying a bit:

`AL=(1)/(12)(8)(3.14)` and a bit more:

`AL=(25.12)/(12)` and finally, to

AL = 2.09 m
