Answer:

$r\approx 1.42 \text{ mm}$

Explanation:

We can solve for
(radius) in the circumference (perimeter) formula:

$C = 2\pi r$

↓ divide both sides by 2π

$r = (C)/(2\pi)$

Then, we can plug the given circumference (
) value into that formula to approximate the radius of the object.

$r \approx (8.9)/(2(3.14))$

$\boxed{r\approx 1.42 \text{ mm}}$
