### H. Volume of Region Common to Intersecting Cylinders

**Problem:**
Sketch the region common to the intersecting cylinders \( x^2 + y^2 \leq a^2 \) and \( x^2 + z^2 \leq a^2 \). Find the volume of this region using a triple integral in Cartesian coordinates. Do the integrals by hand on this one—they should work out easily. 

**Solution:**
- **Answer:** \(\frac{16a^3}{3}\)

### I. Average Temperature of Cylindrical Region

**Problem:**
Set up a triple integral in Cartesian coordinates whose value gives the average temperature of the cylindrical region \( W \) bounded by the planes \( z = 0 \), \( z = 2 \), and the cylinder \( x^2 + y^2 = 1 \). The temperature distribution is \( T = f(x, y, z) = 50e^{x^2 + y^2} \). Evaluate using the Wolfram Alpha widget.

**Solution:**
- **Answer:** 85.9
