Question

Let f and g be the functions given by f(x)=1+sin(2x) and g(x)=e^(x/2). Let R be the shaded region in the first quadrant enclosed by the graphs of f and g.
A. Find the volume of the solid generated when R is revolved around the line y=pi.
B. Fine the volume of the solid generated when R is revolved around the line x=pi

Answer 2

Sorry. I'm really confused though.

Answer 3

I don't know if you'll see this but for a: V=pi times the integral from 0 to 1.13569 of [(1+sin(2x)-pi)^2-(e^(x/2)-pi)^2] dx
I got -4.204 and i don't think it should be negative. And i still am not sure about B. How do i change the bounds,
