Question

Find the volume of the solid generated by revolving the region bounded by
y=e^(5/2x),y=0,x=1, and x=5

about the x-axis.

Answer 1

ok ok ok

I did one. Can you follow my logic and try the others? They're all done the same way. Decide the limits of integration, and then use

discs: v = ∫πr^2 dx
shells: v = ∫2πrh dx

or dy, depending on how you want to integrate. Just decide on r and h, and plug them in.
