Answer:

540 m

Step-by-step explanation:

We are given that

Central angle,\theta=30rad

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\times 30=540 m

Hence, the length of arc=540 m

Answer:

V=90

Step-by-step explanation:

<u>Step 1:  Find the volume of the cone</u>

<u />V = \frac{\pi *r^{2}*h}{3}

<u>Plug in the values</u>

<u />V = \frac{\pi *3^{2}*10}{3}

<u>Simplify and Solve</u>

<u />V = \frac{\pi *9*10}{3}

V = \frac{90\pi }{3}

V = \frac{90*3 }{3}

V=90

Answer:  V=90
