Answer:
1) V = 12 π ㏑ 3
2) 
Step-by-step explanation:
Given that:
the graphs of the equations about each given line is:

Using Shell method to determine the required volume,
where;
shell radius = x; &
height of the shell = 
∴
Volume V = 



V = 12 π ( ㏑ 3 - ㏑ 1)
V = 12 π ( ㏑ 3 - 0)
V = 12 π ㏑ 3
2) Find the line y=6
Using the disk method here;
where,
Inner radius 
outer radius R(x) = 6
Thus, the volume of the solid is as follows:





Recall that:

Then:





The graph of equation for 1 and 2 is also attached in the file below.
Hello from MrBillDoesMath!
Answer:
= (the equal sign)
Discussion:
Note sure if this is what they wanted but 6/5 = 1 1/5 so I'd guess the symbol is "=". That is,
6/5 = 1 1/5
Thank you,
MrB
