Answer:
The correct option is 1. The circumference of circle is 12π units.
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
\(C=2\pi r\)
Where, r is the radius of the circle.
The circumference of the circle is
\(C=2\pi (6)\)
\(C=12\pi\)
The circumference of circle is 12π units.
Therefore option 1 is correct.
