Answer:
480 mm³
Step-by-step explanation:
The volume (V) of a pyramid is
V =  area of base × height, hence
 area of base × height, hence
V =  × 96 × 15 = 32 × 15 = 480
 × 96 × 15 = 32 × 15 = 480
 
        
             
        
        
        
Answer:
-6
Step-by-step explanation:
3n = n² - 54
n² - 3n - 54 = 0
n² - 9n + 6n - 54 = 0
n(n - 9) + 6(n - 9) = 0
(n - 9)(n + 6) = 0
n = 9 , -6
 
        
             
        
        
        
Answer:
Area =  square centimeter
 square centimeter
If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.
Step-by-step explanation:
As we know the circumference of a circle is 
The radius of the hub cap needs to be devised to determine the area
 
 

 centimeters
 centimeters
Area of the hub cap = 
Substituting the devised value of r in the above equation, we get - 

 square centimeter
 square centimeter
If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.
