Respuesta :

Equanimity
The formula for the circumference of a circle is 2•Pi•R (radius)or Pi•D (diameter).
Since we have the Radius, 5, let's use the 2•Pi•R path.
Pi is defaultly used as 3.14

Plug in 5 for R.

2 • 3.14 • 5
2• 5 = 10
10 • 3.14 = 31.4

The circumference of your circle is 31.4 CM.

Answer: 31cm

I hope this helps!
