Answer:
No solution
Step-by-step explanation:
since it equals a negative 3 in the original equation it cannot be solved
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.
406 divided by 140 makes 2.9 multiply that 100 and you arrive at 290%. Hope this helps!
Your numbers would be 6 and -1
