Integrate the area function of the cross-section, A(x), over the interval [a, b] where the solid exists.

The formula for A(x) changes based on the shape (triangle, semicircle, etc.), directly impacting the volume integral.

These values are crucial for defining the area function A(x), which is then used to calculate the volume.

These are the x-values where the solid begins and ends, often found by finding the intersection points of the curves that define the base.

The area between curves defines the base of the solid, and the height of the cross-section is determined by the shape (triangle, semicircle).

Visualization helps understand the shape of the cross-sections and how they vary along the x-axis, aiding in setting up the integral.

The integral sums up the volumes of infinitely thin slices (cross-sections) to find the total volume of the solid.

Cross-sections perpendicular to the x-axis use $dx$, while those perpendicular to the y-axis use $dy$, changing the variable of integration and the limits.

The volume calculation becomes more complex, often requiring adjustments to the area function or a different integration technique.
