we know that
the equation of the circle is of the form
where
(h,k) is the center of the circle
r is the radius of the circle
in this problem we have
so
the center is the point 
the radius is 
therefore
the answer is
The radius of the circle is equal to

Explanation:
Any item in which you can measure (such as length, width, etc) is a continuous variable. These values can take on any positive decimal value. This is why choices A, B and F are continuous.
Choice C on the other hand isn't continuous. It's a discrete value because the number of desks or any item is a positive whole number (1,2,3,...). So having a value like 1.75 desks doesn't make sense. Therefore, we can rule out choice C.
We rule out choices D and E because they aren't quantitative variables. Instead, they are qualitative. They deal with non-numerical aspects of statistics.
It can fly 106*15 = 1,590 miles in 15 hours.
