Answer:
Required volume is unit.
Step-by-step explanation:
Given equations of curves,
,
substitute second in first we will get,
When and
. Thus both curves intersect at the points (4,16),(-4,16). And thus
.
Considering width of the representative rectangle as which is parallel to x-axis because of considering cylindrical shell. Therefore volume of the shell is given by,
Now,
Length of generating box=Length of from line x=4(axis of revolution)=circumference of the shell=(4-x)
Width of box=
Hence,
which is required volume of generating area.
