Step-by-step explanation:
From the given figure it is clear that the radius of the circle is6 units.
The circumference of a circle is
[tex]C=2\pi r[/tex]
Where, r is the radius of the circle.
The circumference of the circle is
[tex]C=2\pi (6)[/tex]
[tex]C=12\pi[/tex]
The circumference of circle is 12π units.
Therefore option 1 is correct.
