Question
**Problem Statement:**

Let \( E \) be the region above the sphere \( x^2 + y^2 + z^2 = 1 \), inside the cone \( z = \sqrt{x^2 + y^2} \), and below the plane \( z = 2 \). Write the triple integral

\[
\iiint_E x^2 \, dV
\]

in spherical coordinates. Do **not** evaluate it.

**Diagram Explanation:**

The problem describes a three-dimensional region defined by:
- The sphere \( x^2 + y^2 + z^2 = 1 \).
- The cone \( z = \sqrt{x^2 + y^2} \).
- The plane \( z = 2 \).

The provided sketch shows the coordinate limits for setting up this integral:
- The integral with respect to \( \theta \) ranges from \( 0 \) to \( 2\pi \).
- The integral with respect to \( \phi \) ranges from \( 0 \) to \( \frac{\pi}{4} \).
- The inner integral with respect to \( \rho \) goes from \( 1 \) to the upper limit defined by the intersection of the shapes.

The problem asks to set up this integral, suggesting that the solution will require determining these boundaries using spherical coordinates and noting the volume element \( dV = \rho^2 \sin \phi \, d\rho \, d\phi \, d\theta \).
