In my mind I was still rotating it about x axis. I apologise for that confusion. The reason for limit 0 to 1 is because cos(x) along y axis is between 0 and 1. Hope that helps. $\endgroup$ –

WebFeb 8, 2024 · I am struggling with a concept of finding the radius in the shell method of finding the volume of the solid when revolved around a line other than the axis. Maybe the issue here is that I am looking for a "rule" instead of actually visualizing the problem. WebThe washer method is perfect for calculating the volume of this figure. Washers perpendicular to the y-axis have the radii shown (→). They were simply found by solving for x from the functions. The area function can then be found from the radii, R1 and R2: A = π [ y 1 / 3) 2 − ( y 1 / 2) 2] = π ( y 2 / 3 − y)

WebConsider Figure 7.3.1, where the region shown in (a) is rotated around the \(y\)-axis forming the solid shown in (b). A small slice of the region is drawn in (a), parallel to the axis of rotation. When the region is rotated, this thin slice forms a cylindrical shell , as pictured in part (c) of the figure. WebSep 11, 2015 · V = (4pi)/3 Looking at the graph of y = 2 - 2x, imagine the area between the line, the x-axis, and the y-axis, being revolved around the x-axis.
