Find the distance between the points `P(3, (3pi)/6)` and `Q(-7, -pi/3)` which are given in polar coordinates.

Explanation

To find the distance between the points \( P(3, \frac{3\pi}{6}) \) and \( Q(-7, -\frac{\pi}{3}) \) given in polar coordinates, we will first convert these points into Cartesian coordinates and then use the distance formula.

### Step 1: Convert Polar Coordinates to Cartesian Coordinates

**Point P:**
Given \( P(3, \frac{3\pi}{6}) \):
1. Simplify \( \frac{3\pi}{6} \) to \( \frac{\pi}{2} \).
2. Use the formulas for conversion:
