Answer:

25,132.74 miles

Step-by-step explanation:

Hello!

We are basically asked to find the circumference of the Earth's cross-section.

Circumference: [tex]C = 2\pi r[/tex]

We can replace 2r with the diameter, because the diameter is 2 times the radius.

Multiply the Diameter by pi:

  • [tex]C = \pi D[/tex]
  • [tex]C = 8000\pi[/tex]
  • [tex]C = 25,132.7412287183 \approx 25,132.74[/tex]

It is around 25,132.74 miles around.
