<li>Let R be the Region enclosed by the graphs of y= e^(-x), x=k (k>0), and the coordinate axes.</li>
</ol>
<p>a.) Write an improper integral that represents the limit of the area of the region R as k increases without bound and find the value of the integral if it exists.</p>
<p>b.) Find the Volume, in terms of k, of the solid generated if R is rotated about the Y-axis</p>
<p>c.) Find the volume, in terms of k, of the solid whose base is R and whose cross sections perpendicular to the X-axis are squares.</p>
<p>I also need help on another calculus question, but there’s a graph. It’s problem number 24 in the link below.
