Please give the best explanation that you can

Thank you!

Step-by-step explanation:

you see that yb=2 and that zc is double yb so zc=4. adn if ay=6 that means double ay= 12 or 8+4=12

So than given that the diameter of a circle is 28 inches so from this result the radius is d/2 = 28/2 = 14 inches 

than the circumference of circle will be equal 2*3,14*14 = 6,28 *14 = 87,92 so rounded equal 88 in.

so this mean that choice c.) is right sure 

hope this will help you
