Answer:

7 feet.

Step-by-step explanation:

<u>Solve</u>

  • Set up a proportion using the given information for the turbine and its model.

C /d =  

C /d

  • Set up a proportion.

660 /210 =  

22/ d

  • Substitute the given values.

660 ÷ 30

210 ÷ 30  ≈  

22/ d

Since 660 divided by 30 is approximately 22, divide 210 by 30 to find the value of d.

660 /210  ≈  

22/ 7

 d ≈ 7

The diameter of the model is approximately 7 feet.
