Answer:

Option C, $31.4\ cm$

Step-by-step explanation:

Step 1: Determine the formula

Formula → $C = 2*\pi *r$

Step 2: Determine the radius

$Radius = \frac{Diameter}{2}$

$Radius = \frac{10\ cm}{2}$

$Radius = 5\ cm$

Step 3: Determine the circumference

$C = 2 * \pi * (5\ cm)$

$C = 10\ cm * \pi$

$C = 31.4\ cm$

Answer: Option C, $31.4\ cm$
