radius = y
h = ln(y)
confirm using washers ...
Hi, I need help with regards to whether or not I've set this up correctly . The question asks," use the method of cylindrical shells to find the volume.... bounded by the given curves
y=e^x, x=0, and y=pi about the X-axis
V=2(pi)rh dy
Interval=1 to pi
radius =y-1
height = ln (y) by solving y=e^x for x=ln y
thickness = dy
So V= ∫[1,pi] 2pi(y-1)(ln(y)) dy
Is this correct? I'm not sure on the radius....
