The answer is C

Answer 7

Yes the answer is C

Answer 8

I was trying to give you the reason why its c

Answer 9

please do @Jazzy17999

Answer 10

okay

Answer 11

C=2PI*r
r=C/2PI=27/6.28 inches
2pi = 6.28
so, you have

2pi r = C
6.28r = 27
now just divide by the 6.28 to get r.
When you divide 27 by 6.28 you get 4.29936305732
rounded is 4.30
As I said before R is C (4.30)

Answer 12
