Find the volume of the region bounded by
y = ln(x), y = 1, y = 2,
x = 0
and rotated about the y-axis. Which method will be
easier for this problem?
2.
Find the volume of the region bounded by
y = 2x + 2, x =
y2-2y
and rotated about y = 2. Which method will be easier
for this problem? NOTE: You do
not need to integrate this problem, just set it up.
Find the volume of the solid obtained by rotating the region
bounded by y = x 3 , y = 1, x = 2 about the line y = −3.
Sketch the region, the solid, and a typical disk or washer
(cross section in xy-plane).
Show all the work and explain thoroughly.
Consider a region R bounded by the y-axis, the line
segment y=8-x for x from 0 to 8, and part of the circle
y=-sqrt(64-x^2) for x from 0 to 8. Find the centroid.
Find the volume of the figure whose base is the region bounded
by y = x^2 + 4, y = x^2, the y-axis, and the vertical line x =2,
and whose cross sections are squares parallel to the x-axis.
