WebDec 28, 2024 · Each slice looks like a disk or cylinder, except that the outer surface of the disk may have a curve or slant. Let’s approximate each slice by a cylinder of height dx, where dx is very small. In fact, I like to think of each disk as being generated by revolving a thin rectangle around the x -axis. WebThe radius of each cylindrical shell is the horizontal distance from the current x value to the axis of rotation. So if we rotate about the line x=2, the distance between our current x position and the axis of rotation is 2-x. Likewise, if we rotate about the y axis (aka x=0) the radius is x-0=x. 3 comments ( 45 votes) Upvote Downvote Flag more signs of allergic reaction to peanuts
