The formula of volume of a washer requires both an outer radius r^1 and an inner radius r^2. This is as simple as subtracting the area of the smaller disc from the larger one. First, we will graph our bounded region.

It’s called the “washer method” because the cross sections look like washers. We’ll also be using our techniques in calculating the area between two curves , so make you remember the key concepts for this topic.

And so our integration looks like: This is as simple as subtracting the area of the smaller disc from the larger one.

Now we can calculate the area of the cross section. The formula involves the area of a circle and is easy to use.

In effect this is the same as the disk method, except we subtract one disk from another. And they have the area of an annulus:

The disks are now washers: The washer method for finding the volume of a solid is very similar to the disk method with one small added complexity.

The inner radius will be the bottom function, which is x. It’s called the “washer method” because the cross sections look like washers.

That is, v = ∫ a b d v = ∫ a b π [ f ( x)] 2 d x. There is one key difference this time around:

This is as simple as subtracting the area of the smaller disc from the larger one. Since the washer method uses a similar process as the disk method, it’s important that you have understood the math behind the disk method.

In our case r = x and r = x 3. Volume between the functions y=x and y=x 3 from x=0 to 1. Solid of revolution between two functions (leading up to the washer method) generalizing the washer method.

In This Method, We Slice The Region Of Revolution Perpendicular To The Axis Of Revolution.

Volume of a solid of revolution: In effect this is the same as the disk method, except we subtract one disk from another. Finding the volume using the washer method around other axes.

The inner radius will be the bottom function, which is x. And so our integration looks like: When we use the washer method, the slices are perpendicularparallel to the axis of rotation.
