56.55

Step-by-step explanation:

The formula for circumference is [tex]C = \pi d[/tex] or [tex]C = 2 \pi r[/tex]

Answer:

56.52

Step-by-step explanation:

Circumference is [tex]C=2\pi r[/tex]

We are given the radius of 9 in.

Using 3.14 for pi:

[tex]C=2 * 3.14 *9\\\\C=6.28*9\\\\\boxed{C=56.52}[/tex]

The circumference of the circle should be 56.52 inches, your answer should be correct.
