First of all, your imgur link isn't working.

Next, what were you trying to solve with your attempt? Surface area?

Graph the function and notice that getting the integral of the interval from 0 to e is not what you want. Maybe it would give you a more meaningful answer if you separate it into two integrals? Recall what exactly it is an integral gives you when evaluated.

Find where y = lnx and y = 0 intersects. Then use those bounds. Should be easy enough for you.

Same answer, different path taken. Honestly, just look at the picture it would make. It turns into simple subtraction.
