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: The mass of solid a is 4800 grams

Step-by-step explanation:

Hi, to answer this question we have to apply proportions:

For solid b = 40.32 cm2 / 6912 grams

For solid a = 28 cm2 / x grams

Where x is the mass of solid a.

So:  

40.32 / 6912 = 28 / x  

x = 28 / (40.32 / 6912)

x = 4800 grams

The mass of a is 4800 grams

Feel free to ask for more if needed or if you did not understand something.
