**Understanding the Equation of a Circle**

The standard form of the equation of a circle is \((x - h)^2 + (y - k)^2 = r^2\), where:
- \((h, k)\) is the center of the circle.
- \(r\) is the radius of the circle.

### Example Problem

Consider the following equation of a circle:

\[
(x - 10)^2 + (y - 8)^2 = 256
\]

**Question:** What is the center of the circle?

**Solution:** 

To determine the center of the circle, we compare the given equation with the standard form \((x - h)^2 + (y - k)^2 = r^2\).

From the given equation:
- \(h = 10\)
- \(k = 8\)

Therefore, the center of the circle is \((10, 8)\).
