Question

Find the length of the​ arc, s, intercepted by the given central​ angle, thetaθ​, in a circle of​ radius, r. θ=30 ​rad; r=18 m.

Answer 1

540 m

Explanation:

We are given that

Central angle,
`\theta=30`rad

Radius of circle=18 m

We have to find the length of the arc s.

We know that

Length of arc,
`s=r\theta`

Using the formula then, we get

Length of arc,
`s=18* 30=540 m`

Hence, the length of arc=540 m
