Question

Find the arc length if the measure of the central angle is 80° and the radius
is 8 inches.

Answer 1

`(32\pi )/(9)` or
`11.17`

Explanation:

• The formula for arc length is
  `2\pi r( (x)/(360) )` where "r" stands for radius and "x" stands for your angle

`2\pi 8((80)/(360) )`

`=16\pi ((80)/(360) )`

`=16\pi ((2)/(9))`

`=(32\pi )/(9)`
