Question

Π (pi) is an unending decimal. Find the Circumference of the circle below using exact π (pi).

Answer 1

Step-by-step explanation:

Given radius, r = 5,

Circumference of Circle, C

$= 2\pi \: r \\ = 2\pi(5) \\ = 10\pi \: units$

Answer 2

Answer:

$10\pi$

Step-by-step explanation:

As the hint below says:

$C = 2\pi r$

We also know that

r = 5

So thus:

$C = 2 \pi \cdot 5 = 10\pi$
