Find the circumference of a circle with diameter of 10 cm.

Answer:
Option C, [tex]31.4\ cm[/tex]
Step-by-step explanation:
Step 1: Determine the formula
Formula → [tex]C = 2*\pi *r[/tex]
Step 2: Determine the radius
[tex]Radius = \frac{Diameter}{2}[/tex]
[tex]Radius = \frac{10\ cm}{2}[/tex]
[tex]Radius = 5\ cm[/tex]
Step 3: Determine the circumference
[tex]C = 2 * \pi * (5\ cm)[/tex]
[tex]C = 10\ cm * \pi[/tex]
[tex]C = 31.4\ cm[/tex]
Answer: Option C, [tex]31.4\ cm[/tex]
