Center is at $\left(4 , 0\right)$.
Radius is $\frac{4}{5}$.

#### Explanation:

The formula for a circle is:
(x – h)^2 + (y – k)^2 = r^2
where $\left(h , k\right)$ is the center, and $r$ is the radius.

${\left(x - 4\right)}^{2} + {\left(y - 0\right)}^{2} = {\left(\frac{4}{5}\right)}^{2}$

$\left(4 , 0\right)$ is the center.
$\frac{4}{5}$ is the radius
