Here is the question:
I have posted a link there to this thread so the OP can view my work.How to find the volume of a solid given an equation and bounds?
Let the first quadrant region enclosed by the graph of =1/x, x=1 and x=4 be the base of a solid. If cross sections perpendicular to the x-axis are semicircles, the volume of the solid is:
(Answer: 3pi/ 32)
Please tell me how you got the answer because I kept getting 3pi/4
