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.
