A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.
The key information here is that the polygon is
inscribed in a circle.
This means all sides of the polygon are INSIDE the circle.
Consider this 12-sided polygon inscribed in a circle (the results here can be expanded to a 24-sided polygon).

Now consider points A and B.
We can see that the distance from A to B along the
STRAIGHT line is
shorter than the distance along the
CURVESo, we can say that the sum of all of the
STRAIGHT lines must be
shorter than the sum of the
CURVED distances.
In other words, the perimeter of the
polygon must be
less than the sum of the circumference of the
circle.
Answer: B
