Answer: (2,0),(−2,0)
Step-by-step explanation:
I think you have to count 85 and go down like 85 86 87so the answer is 15
c = circumference
pi = 3.14
r = radius = 9 inches
d = diameter
c=pi*d
The radius is half of the diameter, d = 2r. Then d = 2*9=18.
plug into equation. c= pi*d = 3.14*18
round accordingly and you may want to include that the measurement you end up with is in inches.
