The second method to get the volume of revolution is by doing the Washer Method. The washer method applies when the solid is partially or fully hollow.

**Examples covered in this video series:**

1. Find the volume given by rotating the region bounded by f(x) = x +2 and g(x) = x + 1, y =0, x =0, x =5 about the x-axis

2. Find the volume of the solid formed by revolving the region bounded by the graphs y = 2x and y = x^2 about the x-axis.

3. Find the volume of the solid formed by revolving the region bounded by f(x) = e ^(x/2) + 1, y = 1, x =0 and x =4 about the x-axis.

4. Find the volume of the solid formed by revolving the region bounded by f(x) = x^3 + 2, x = 0, y = 2 about the y-axis.

4b. Find the volume of the solid formed by revolving the region bounded by y = x^3 + 2, x = 0, x = 1, y = 0 about the y axis.
