The only difference with the disk method is that we know the formula for the cross-sectional area ahead of time; it is the area of a circle. This gives the following rule.

Disk Method Formula The disk method is used when the axis of revolution is the boundary of the plane region and the cross-sectional area is perpendicular to the axis of revolution. This …

And that is our formula for Solids of Revolution by Disks In other words, to find the volume of revolution of a function f (x): integrate pi times the square of the function.
