Find the volume of the solid of revolution formed by rotating the bounded region about the x-axis.
f(x)=e-x, y=0, x=-2, x=1.

27.11514 pi

Step-by-step explanation:

Given is a function exponential as

The region bounded by the above curve, y =0 , x=-2 x =1 is rotated about x axis.

The limits for x are -2 and 1

The volume when rotated through x axis is found by

Here a = -2 and b =1

volume =

=

13.46

step-by-step explanation:

16.80 x .20 = 13.46
