According to the given situation, the calculation of volume of the solid is shown below:-
Here we will consider the curves that is

Now, rotating the line for the line x which is equals to 7

So, the inner radio is
7 - 7 = 0
and the outer radius is

Now, the area of cross section is

The volume is

now we will put the values into the above formula

After solving the above equation we will get

Answer:
(-2+4)/2
= 1
(-4-8)/2
= -6
(1,-6) is the midpoint of the line
