technical calculus problem
I hate that my first post on this forum is a question!! These are two questions I can not figure out:
1. Find the volume of the solid of revolution obtained by rotating R, defined by the bounds given in each exercise, about the y-axis.
2. Find the volume of the solid obtained by revolving the region bounded by y=square root of X , x=4
a. the x axis
b. the y axis
c the line x=5
d. the line y=3
I don't just need the answer, I need to understand what I need to do to get the answer. Thanks for any and all help.
