Answer:

B.5.1 cm

Explanation:

Hello, I think I can help you with this

the circumference of a circle is given by:

$s=2*\pi *radius$

Step 1

Let

s=32 cm

radius=?

isolate the radius from the equation

$s=2*\pi *radius\\(s)/(2\pi ) =radius\\s=32,so\\radius=(32)/(2\pi ) \\radius=5.1\ cm$

5.1 cm ⇔B.
