Volume by Revolution: Shell Method around Non-Axis

Volume by revolution problem where the axis of revolution is not the y-axis or x-axis but the vertical line x=4

Thanks so much man, Ive been searching for hours on what to do when a specific number axis is given but couldn’t find it anywhere, thanks for all ur help

[@paradoxalproof9796]

Glad it helped!

I was struggling trying to figure out the radius on my own but this really really helped. Thank you

H, the height of the partition parallel to the axis of rotation, should be subtracted by top-bottom, not right-left. Right-left is for when the axis of rotation is horizontal, as the partition will be laying down instead of standing up.

I really appreciate this video! THANK YOU

Thanks, this really helps on finding the radius.

Thank you so much for explaining why you would use shell not disk

[@nico3727]

Also including how to check!!!!

[@treemanfan7718]

what conditions will the problem have to be for you to use right - left.

[@jakobsime4190]

The conditions seen in the video is right - left. Right (axis) minus left (x)

[@paradoxalproof9796]

With the shell method and when you are finding the radius of the shell, if the functions are in terms of x (as seen in the video), then it is right - left. If the function is in terms of y (such as x=y^2 + 2), then it will be top - bottom axis
