Consider the shaded region in the figure below and answer the
following questions.
$x+2y=2$
1. An definite integral in terms of $x$ for finding the volume of the
solid generated by revolving the shaded region about the $x$-axis
is:
$\int_a^b \pi [\frac{f(x)}{2}]^2 dx$
Identify the values of a, b and function $f(x)$, respectively.
$a=0$
$b=2$
$f(x)=1-x$
2. An definite integral in terms of $y$ for finding the volume of the
solid generated by revolving the shaded region about the $y$-axis is:
$\int_c^d \pi [g(y)]^2 dy$
Identify the values of c, d and function $g(y)$, respectively.
$c=0$
$d = 1$
$g(y)=2-2y$
Note: Your answers to $f(x)$ and $g(y)$ should be simplified as much
as possible.
