From the figure, the coordinates center of the circle is (x, y)=(-1, -2).
The horizontal distance from the center of the circle to one point of the circle gives the radius of the circle.
So, the radius of the circle is r=4.
Now, the circumference of the circle can be calculated as,
[tex]\begin{gathered} C=2\pi\text{ r} \\ =2\pi\times4 \\ =25.1\text{ units} \end{gathered}[/tex]Therefore, the approximate circumference of the circle is 25.1 units.
Option B is correct.
