Step-by-step explanation:
Answer:
F. 
Step-by-step explanation:

Cross multiply:
7b= 2(a +2b)
Expand:
7b= 2a +4b
Bring all common variables to 1 side:
7b -4b= 2a
3b= 2a
divide by 2 on both sides:

divide by b on both sides:

Answer:
Option b
Step-by-step explanation:
given that a region is bounded by the curves 
It is rotated about x axis
We are to use shell method
Region picture is enclosed
We are to use shell method
Due to symmetry we can find form 0 to 2 and double it.
Here limits for y are from 0 to 2
The variable x can be written as

A(y) = area = 
Volume = 
Hence option b is right
volume of the solid
