All you need to do is use the formula to solve. What I do is I plug in the information that I know, and then I just solve. In this case it would be: 
V= (4)
       -    pie(3.14)*4.8(cubed) 
       3 
I hope I was a good help, and if you still need help, come to my page and ask the question on specifically what you need help with. :D

Answer:
10t - 16
Step-by-step explanation:
4(t + 2)+ 6(t - 4)
4t + 8 + 6t -24
10t - 16
 
        
                    
             
        
        
        
According to the identity if a+b+c=0
then a3+b3+c3=3abc
a3+b3+c3/abc=3
a2*a/bc*a+b2*b/ca*b+c2*c/ab*c=3
cancel a,b,c in   all the fraction then you get
<span>a²/bc+b²/ca+c²/ab=3. 
</span>hence proved
