Disk method - The disk volume method calculator operates by applying integral calculus principles to compute the volume of three-dimensional solids generated through the method of revolution. When a two-dimensional shape, typically represented by a mathematical function or curve, is rotated around an axis— typically the x-axis or y-axis— it forms a solid.

 
The disk method involves dividing an object into many small disks or cylinders and then adding the volumes of these small disks together to determine the object’s volume. A cylinder’s radius is given by a function f(x), and its height is determined by x. When the change in x reaches zero and the number of disks increases to infinity, you .... Its about damn time

For any given x-value, the radius of the shell will be the space between the x value and the axis of rotation, which is at x=2. If x=1, the radius is 1, if x=.1, the radius is 1.9. Therefore, the radius is always 2-x. The x^ (1/2) and x^2 only come into play when determining the height of the cylinder. Comment.
