Hi Again. I am sorry, but I madr an error in the integral for the second part of your exercise. I'm sure you'll see it easily enough. The integrand to get volume by shells should be 10/x. Sorry friend. I solved it in my ubiquitously messy way, then copied it down on the sheet with the plots. The solution, happily, is therefore, still accurate.

Be well,
