To evaluate the given integral, we need to change to spherical coordinates. Let's start by rewriting the integral in terms of $x$, $y$, and $z$ and then express these in spherical coordinates. The given integral is:

$\int_{0}^{10} \int_{0}^{\sqrt{100 - x^2}} \int_{x^2 + y^2}^{200 - x^2 - y^2} yz \, dz \, dy \, dx$

Step 1: Express in Spherical Coordinates

In spherical coordinates:

• $x = \rho \sin \phi \cos \theta$
• $y = \rho \sin \phi \sin \theta$
• $z = \rho \cos \phi$
• The volume element $dV = \rho^2 \sin \phi \, d\rho \, d\phi \, d\theta$

Step 2: Limits of Integration

The given bounds for $x$, $y$, and $z$ define a region in space, which we’ll interpret in spherical coordinates.

1. $x$ ranges from $0$ to $10$, which suggests a limitation on $\rho \sin \phi \cos \theta$.
2. The inner bounds on $y$ and $z$ suggest circular regions, further implying a spherical domain.

To make this transformation concrete, let’s set up the integral accordingly.

Here are some related questions to deepen understanding:

1. How do you determine the limits for spherical coordinates from Cartesian bounds?
2. Why is the volume element $dV$ different in spherical coordinates?
3. How does symmetry help in evaluating triple integrals?
4. Can this integral be simplified by symmetry arguments before converting?
5. How does one handle trigonometric terms like $\sin \phi \cos \theta$ in integrals?

Tip: When transforming coordinates, always remember to include the Jacobian determinant in the volume element.
