I've been working on this problem for while, and I keep getting the answer wrong every time I do it.

Question

The volume of the solid obtained by rotating the region enclosed by

y=e^(5x+1) y=0 x=0 x=0.8

about the x-axis can be computed using the method of disks or washers via an integral:

(what I set it up as)
intg(pi(e^(5x)+1)^(2)) with a=0 and b=0.8

The last answer I got was wrong and it was 6917.5. Please, I need help working out this home work problem! Thanks!

Answer 1

Never mind! I figured it out!
