1. Using washers, the volume is given by the integral
We're using washers whose centers depend on the value of 
, hence we integrate with respect to
2. The area of the given region is given by the integral
To compute the integral, first consider the substitution 
, or 
so that 
. Then 
and 
, so the integral is equivalently
Integrate by parts, taking
so that
and 
, so the area is
For the remaining integral, substitute 
, so that 
. Then 
and 
:
(notice that the integral is improper)
