8.11 Volume with Washer Method: Revolving Around the x- or y-Axis question 1

[Maximum number: 1]

The region bounded by y=ex,y=1y=e^{x}, y=1, and x=2 is rotated about the x-axis. The volume of the solid generated is given by the integral:

A

integral from 0 to 2 of e squared x end exponent dx

B

i integral from 0 to 2 of left parenthesis e to the power of x end exponent minus 1 right parenthesis squared end exponent d x

C

i integral from 0 to 2 of left parenthesis e squared x end exponent minus 1 right parenthesis d x

D

integral from 1 to

E

squared of left parenthesis 4 minus natural log squared end exponent y right parenthesis d y
