I know how to do area problems but not with e, so i would appreciate the help.

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Then find the area of the region.

y = e^(5 x)

y = e^(6 x)

x = 1

I'm not sure if i'm suppose to rotate it around x=1, which means i need to change it in terms of x. and then i need to find the points and integrate the square of the difference between the e's (but i don't know how to square those terms either)

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

y = e^(3 x)+4

y = 0

x = 0

x = 0.1

for this problem i'm sure you just integrate pi * the square of y = e^(3 x)+4 from 0 to 0.1, but I don't know how to square y = e^(3 x)+4.

any help would be appreciated.
