the correct question is
The orbit of the space shuttle is approximately a circle with a radius of 4100 mi. How far do
the astronauts travel with each orbit?
we know that
[the circumference of a circle]=2*pi*r
for r=4100 mi
[the circumference of a circle]=2*pi*4100-----> 25761.06 mi
the answer is
25761.06 mi
