Answer:

18.8 inches

Step-by-step explanation:

The circumference is [tex]\displaystyle{C = 2\pi r}[/tex]. The diameter is two times of radius which can be expressed as [tex]\displaystyle{d = 2r}[/tex].

We can rewrite the equation of circumference as [tex]\displaystyle{C = \pi d}[/tex]. Thus, substitute d = 6 in:

[tex]\displaystyle{C = 6\pi}\\\\\displaystyle{C = 18.849}[/tex]

Rounding to the nearest tenth, we will get:

[tex]\displaystyle{C = 18.8 \ \sf \ inches}[/tex]

Hence, the circumference is 18.8 inches.
