The answer is not possible because both most common factors cancel each other out
        
                    
             
        
        
        
Answer:
y=3
Step-by-step explanation:
 
        
                    
             
        
        
        
H=1in
You would need to use the equation V= pie times radius squared times height. Since it gives you the diameter, you would need to divide 3 by 2 to get 1.5. So now you would plug in 7.1=pie×1.5(squared)×h
Now solve the equation to get 1in. 
And you can check this answer by using this same equation to plug in pi×1.5 (squared)×1 and you will get 7.1 as your volume.
