How to Use This Calculator

Select the function f(x) that will be revolved, and enter its defining parameters.
Set the bounds of integration (a to b) along the x-axis — the solid extends across this interval.
Choose the Disk Method (revolution around x-axis): V = π ∫[a,b] [f(x)]² dx.
Choose the Shell Method (revolution around y-axis): V = 2π ∫[a,b] x·f(x) dx.
The cross-section profile chart shows the radius of the solid at each x value, representing half the disk diameter.
Both methods produce the same volume for the same region — choose based on which integral is easier to set up.
