A hyperbola with a center at (0, 0) can be defined  as x²/a² − y²/b² = ±1.<span> 
</span>The statement "<span>The symmetry of a hyperbola with a center at (h, k) only occurs at y = k" </span>is false, because a hyperbola have many different orientations.
It doesn't have to be symmetric about the lines y = k or x = h.
        
             
        
        
        
Answer:
2408.55 cubic yards
Step-by-step explanation:
use pi times radius squared times height, then divide by 3
 
        
             
        
        
        
For this case we have the following expression:
  
 Using the associative property we can rewrite the expression in the following way:
  
 Finally, simplifying we have:
  
  
 Answer:
 Rewriting the expression we have that the result is:
 d. -7
