Answer:
1/3
Step-by-step explanation:
1/2 James' fraction of Michael
2/3 Trina's fraction of James 
1/2 x 2/3 = 1/3
 
        
             
        
        
        
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.
