The closest measurement is 15.7

Step-by-step 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
