    Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified line.

    y =e^(x)
    y =1
    x =2 ; about y=2

    washer method ...

    V = \pi \int_0^2 (2-e^x)^2 - (2-1)^2 \, dx

    I made a typo, it should be y=e^(-x)

    so will the equation remained unchained except for e^x and should be changed to e^-x
