The formula for a cone is pi * r^2 * (h/3) or pi* r^2 * h * 1/3.
Since the height is 7ft and the radius if 4ft you plug those into the equation and get:
V= 1/3 * pi * (4^2) * (7)ft cubed which is the answer of B
 
        
                    
             
        
        
        
Answer:

9 divided by 803 = 0.01120797
        
                    
             
        
        
        
28:12
equals...
D...
because 28 and 12 are both able to divided by 4, so if you divided them by 4, it is 7 to 3, (REMEMBER ORDER IS IMPORTANT) so the answer is D. 
ANSWER: D
