<div>"Find the volume of the solid formed by revolving the region bounded by y = sqrt(x) and the lines y = 1 and x = 4 about the line y = 1."</div>
<div>I've tried a number of different things, most notably stuff along the lines of pi * ∫ |(1 - sqrt(x))<sup>2</sup>| dx, with the integral being from 0 to 4. I feel like the correct answer should be 4/3 * pi (if you separate the two solids, that'd be pi/6 + 7pi/6), however, the only answers I have to choose from are:</div>
<div>(15/2)pi <br />(5/3)pi <br />(14/3)pi <br />(7/6)pi</div>
<div>I've been staring at this problem for much longer than is healthy. I must be doing something wrong. Thanks for the help.</div>Thu, 17 Aug 2017 02:53:09 -05002017-08-17T02:53:09-05:00
