number one
Step-by-step explanation:
if if 4.5 - 2.5 the answer is 2 that means the answer is number one
 
        
                    
             
        
        
        
When you divide a number by two, you find the number that if you add it to itself, become the original number. 
When you square root a number, you find the smaller number that becomes the bigger number if you multiply it by itself.
For sixteen, if you divide it by two, you get 8, while if you square root it, it becomes 4.
        
                    
             
        
        
        
Sample Response: The base area , radius, and diameter can be
determined when given the volume and height of a cone. Substitute the
values for the corresponding variables into the formula, and then solve
by simplifying and undoing operations to isolate the variable. To find
the diameter, double the radius.
