The Earth has a diameter

Mathematics
1 answer:
mrs_skeptik [129]2 years ago
4 0

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

Tomtit [17]
The complete question in the attached figure

we know that
<span>The measure of the external angle is the semidifference of the arcs that it covers.
so
</span><span>m∠BED =(1/2)*[mAC-mBD]-------> solve for mBD
mBD=mAC-2</span>m∠BED
mBD=80-2*25--------> mBD=30°

the answer is
mBD=30°
