Detailed explanation:
Hii, I'd love to help you out! (:
This problem is all about circles; how fun!
What we need to do is find the circumference of a circle with a 5-cm radius.

Yepp! This is only fun if we're familiar with the required formula.
The formula is shown below.
[tex]---\twoheadrightarrow\sf C=2\pi r[/tex]
Here "C" denotes the circumference,
"[tex]\pi[/tex]" denotes the number pi, *
and "r" denotes the radius.
This question provides us:
[tex]\searrow[/tex]
* The number pi is an irrational number, which means we cannot write it as a fraction, no matter how hard we try. Can you imagine this? There are infinitely many digits after its decimal point.
So what I'm going to do is use 3.14 for pi
3.14.....∞ Wow!

Alright, so now it's time... to have fun solving for the circumference!
[tex]---\twoheadrightarrow\sf C=2\cdot3.14\cdot5[/tex]
[tex]\bullet[/tex] Multiply
[tex]---\twoheadrightarrow\sf C=31.4\;\;cm[/tex]
That's all! See, it's ez as winking (;
Voila! There's our answer!
