Answer:
The answer to your question is r = 2x
Step-by-step explanation:
Volume of a cylinder = V = π r² h
r = radius
h = height = x
Volume = 4x³
Then
                   r² = 
                   r² = 
                   r² = 4x²
                   r = 2x
 
        
             
        
        
        

we can rewrite it as

we can see that 1/4 is in multiple in both terms
so, we can factor it out
so, we get
