I introduce the process of finding the volume of a solid, also called volume of revolution, using the Disk Method and Washer Method. There are a few minor copy errors corrected with annotations. Please read notes if not using Flash.

Example revolving about the x-axis 10:14

Example revolving about the y-axis 15:03

Example revolving about x=4 18:42 PLEASE NOTE: at minute 20:53 I say R(x), that should be R(y) because of the vertical axis of rotation.

Example of a solid with a hole 24:46 PLEASE IGNORE THE INCORRECT DECIMAL APPROXIMATION ANSWER at 28:32. The exact value is correct. Sorry for the error.

Example of two intersecting functions 29:14 PLEASE NOTE: I labelled the intersection of these 2 graphs incorrectly, it should be (3,11)

I would like to send out a HUGE THANK YOU to my YouTube student Jigyasa Nigam that did the Closed Captioning of this lesson for me. Your support and help is greatly appreciated:D
