    Answer:

    The closest measurement is 15.7

    Step-by-step explanation:

    The formula for circumference is [tex]2\pi r[/tex]

    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 · [tex]\pi[/tex] · 2.5 ≈ 15.71

    The closest measurement is 15.7
