Step 2
Now we can say that the volume of the solid created by rotating the region under y = 6e-x and above the x-
axis between x = 0 and x = 1 around the y-axis is
V =

Use the method of cylindrical shells to find the volume V generated by rotating the region bounded by the
given curves about the y-axis.
y = 6e-x?
y = 0,
x = 0,
x = 1
Sketch the region and a typical shell.
