The Earth has a diameter

mrs_skeptik [129]

Answer:

<em>L = 24,873.6 miles</em>

Step-by-step explanation:

<u>Length of the Circumference</u>

Given a circle of radius r, the length of the circumference, or line surrounding the shape is:

$L =2\pi\cdot r$

The Earth has a diameter of 7,917.5 miles. The radius is half the diameter:

r=7,917.5/2=3,958.75 miles

Assuming a plane flies around the equator at ground level, the distance it would travel is:

$L =2\pi\cdot 3,958.75\ miles$

L = 24,873.6 miles
