Use double integration to find the volume of each solid.
The solid bounded above by the paraboloid $z=9 x^{2}+y^{2}$ below by the plane $z=0,$ and laterally by the planes $x=0$, $y=0, x=3,$ and $y=2$.

Key Concepts

Double Integration

Double integration is a technique in multivariable calculus used to compute the integral of a function over a two-dimensional region. It involves integrating with respect to one variable while treating the other as constant, and then integrating the resulting expression with respect to the second variable.

Volume Calculation Using Double Integration

Calculating volume by double integration involves integrating the function that describes the height of the solid above each point in a planar region. When a solid is bounded above by a surface and below by the plane, the volume is the double integral of the function representing the top surface over the region in the base plane.

Setting Up Integration Bounds

Setting up the limits of integration correctly is crucial when performing double integrals. This involves identifying the region in the plane over which the integration is performed, typically determined by the intersections of lines or curves that bound the solid. The limits are chosen to match these boundary conditions.

Choosing the Order of Integration

Choosing the proper order for integration, whether to integrate with respect to x before y or vice versa, depends on the shape of the region and the complexity of the resulting integrals. A well-chosen order can simplify the computation by providing constant or easily integrable bounds for one of the variables.
