Answer:
False
Step-by-step explanation:
The volume of a right cylinder is given by the formula: 

And the volume if a oblique cylinder is <em>also</em> given by the formula: 

Regardless of the height, if the radius are different, then the volume would not be the same.

Answer:
vertex is at (0,0)
Step-by-step explanation:
Find the vertex of the parabola y = 8x2.
I assume you meant   y =  8* x^2
this can be compared to the general vertex form  y = a (x - h)^2 + k
where vertex at  (h, k)
so then...
h =0  and k = 0 here
vertex is at (0,0)
 
        
             
        
        
        
Since the number is 8 you round up so it's 9.0
