we have

substitute


step 2
Find the approximate length of arc s
we know that
The circumference of the circle subtends a central angle of 360 degrees
so
using proportion
Find out the length of arc for a central angle of 330 degrees

----> exact value
assume

----> approximate value
the first graph is (x+20)/x
the second graph is x/(x-20)
