Step-by-step explanation:
30 , 60 , 90 , 120, 150
,LCM of 12 and 30 is 60 
 
        
                    
             
        
        
        
Answer:
mean=sum of data/no of data
=12/3
=4
Step-by-step explanation:
therefore mean=4
 
        
                    
             
        
        
        
The absolute value of a number can never be negative. That's because it represents the distance of a number from zero on a number line. The number 

 is 

 digits to the left of zero on a number line. So, the absolute value of 

 would be 

 .

Answer:
84
Step-by-step explanation:
7*2*8 
L*W*H
 
        
                    
             
        
        
        
if it has a diameter of 8, that means its radius is half that, or 4.
![\bf \textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}~~
\begin{cases}
r=radius\\
h=height\\[-0.5em]
\hrulefill\\
r=4\\
h=5
\end{cases}\implies V=\cfrac{\pi (4)^2(5)}{3}\implies V=\cfrac{80\pi }{3}
