Answer:
The circumference is [tex]$ 4\pi $[/tex]
Step-by-step explanation:
Circumference of a circle is given by : [tex]$ 2 \pi r$[/tex]
where [tex]$ r $[/tex] is the radius of the cirlce.
Here the radius is 2. Substituting in the equation we get;
Circumference = [tex]$ 2 \times \pi \2 = 4\pi $[/tex]
