The london eye is a giant ferris wheel on the south bank of the river thames in london, england. the height of the entire structure, including the support frame, is 135 meters. the wheel has a diameter of 120 meters. find the circumference of the wheel.

To find the circumference of the wheel, you will use the formula for finding the circumference of a circle.

C = pi x d
      3.14 x 120 
C = 376.8 m

The approximate circumference of the wheel is 376.8 meters.
  

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
