Answer:

F. 48.98 m

Step-by-step explanation:

What is circumference?

  • The circumference of a circle is the distance around the circle, otherwise known as the perimeter.
  • The formula to find the circumference of a circle is 2πr, or if you're given the diameter, πd

How does it apply here?

  • We are asked to find the closest circumference given of the swimming pool. We are also given the radius of the pool as 7.8 meters.

Solving

Step 1: Plug in your values.

  • [tex]2 * 3.14 * 7.8[/tex]

Step 2: Simplify.

  • [tex](2*3.14)*7.8 = 6.28 * 7.8[/tex]
  • [tex]6.28 *7.8 = 48.984[/tex]
  • 48.984 ≈ 48.98

Therefore, the correct answer is F. 48.98 meters.
