Find the equation of the circle whose centre is `(2, -2)` and radius is 8.

Explanation

To find the equation of the circle with center at (2, -2) and radius 8, we can follow these steps:

### Step 1: Write down the standard equation of a circle
The standard equation of a circle with center (h, k) and radius r is given by:
\[ (x - h)^2 + (y - k)^2 = r^2 \]
