Answer:

The closest measurement is 15.7

Explanation:

The formula for circumference is
$2\pi r$

The diameter is double the radius, so to get the radius we divide by 2.

5 divided by 2 is 2.5

Knowing "r" is 2.5 we can plug that into our equation and solve.

2 ·
$\pi$ · 2.5 ≈ 15.71

The closest measurement is 15.7
