Answer:
12742π Km
Step-by-step explanation:
The length of the rope is the circumference of the circle, that is
C = 2πr ( r is the radius ) Here r = 6371
C = 2π × 6371 = 12742π Km
For this case we have that by definition, the equation of the line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
By definition, if two lines are parallel then their slopes are equal.
We have the following line:

Thus, the slope is:
Then 
So, the line is of the form:

We substitute the point
and find b:

Thus, the equation is:
