WebMar 18, 2015 · The formula used by Wolfram Alpha is V = 2 π ∫ − 1 1 ( 1 − y) ( 1 − y 3) d x. Here, 1 − y is the height of the cilinder and 1 − y 3 is the radius (the cylider has as axis the line y = − 1). In my opinion this formula is wrong. WebUpvote Justin Freeman 10 years ago You could do this with the shell method (integrating in x)--or you could solve for x = sqrt (1+y) and then use the disk/washer method (integrating in y). The shell method is only required when it is not possible to solve for x in terms of y (though sometimes it is easier anyway). ( 5 votes) rvbcabooservb song how great is our god lyrics
