Question

Find the length of each arc .

Answer 1

A.
`12\pi` mi

Explanation:

Length of arc = r∅

Where,

Radius (r) = 16 mi

Angle in radians (∅) =
`(3\pi)/(4)`

Plug in the values

Length of arc =
`16*(3\pi)/(4)`

Length of arc =
`(16*3\pi)/(4)`

Length of arc =
`(4*3\pi)/(1)`

Length of arc =
`12\pi`
