Question

R = 4 in., θ = 11 rad; find s

Answer 1

The arc length s = 44 inches

Explanation:

We are given:

r = 4 in

Ф = 11 radians

We need to find s

The formula used is:
`s=r\theta`

where s represents arc length, r is radius and Ф is angle in radians

Putting values and finding s

`s=r\theta`

Put r = 4 and Ф = 11

`s=4* 11\\s=44`

So, the arc length s = 44 inches
