Answer:

18.8 inches

Step-by-step explanation:

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

We can rewrite the equation of circumference as $\displaystyle{C = \pi d}$ <em>. </em>Thus, substitute d = 6 in:

$\displaystyle{C = 6\pi}\\\\\displaystyle{C = 18.849}$

Rounding to the nearest tenth, we will get:

$\displaystyle{C = 18.8 \ \sf \ inches}$

Hence, the circumference is 18.8 inches.
