Integral Volume Question
The problem is as follows:
What is the volume of the solid of revolution obtained by rotating the region bounded by the curves
x = y 3 − y 4 and x = 0 about the line y = −2?
My question is why would it make any difference to the volume if the solid was revolved around y= -2 as opposed to y= 0 (or any other number for that matter)?
Disregard this post. I have worked it out with the assistance of Paul's online calculus tutorial. Great graphics helped.
because the location of the axis of rotation affects the radius of rotation, thereby changing the volume.
