The formula for the circumference of a circle is:

$C = 2\pi r$

Where:

• $C$ is the circumference,
• $\pi$ is approximately 3.14,
• $r$ is the radius.

Given that the circumference $C = 56.5$ inches and $\pi = 3.14$, we can solve for the radius $r$ as follows:

$r = \frac{C}{2\pi}$

Substitute the given values:

$r = \frac{56.5}{2 \times 3.14}$

Now calculate:

$r = \frac{56.5}{6.28} \approx 9.0$

Therefore, the radius of the circle is approximately 9 inches.
