## Homework Statement

Find the volume of the solid formed by rotating the region enclosed by:

(e^(1x)+2)/y=0/x=0/x=.9

about the y axis

## Homework Equations

Probably disk method i would assume:

V=pi*int((f(x)^2) dx from bounds a to b

## The Attempt at a Solution

V= pi*int(e^(1x)+2)^2) a=0 b=.9

v=pi*int(e^(2x)+4) a=0 b=.9

v=pi*(1/2e^(2x)+4x)

v=pi*(1/2e^(2(.9))-(1/2e^0)+(4(.9)

v=pi*(3.025)-(1/2)+3.6

v=6.125pi

But my answer is not correct.
