Rational numbers are numbers which can be written as a fraction (the formula is p/q). They don't include roots we can't solve in order to get a whole number and pi.

A. 776, pi, 25.209, √9   --->    NO (because of pi)
B. 726, 7/34, 20.209, √9    --->   YES
C. √3, 7/39, 20.3, √9   --->    NO (because of √3)
D. 726, 7/34, 20.209, √5   --->   NO (because of √5

Note that √9 = 3, so it IS a rational number.

Answer:

Option (B) is correct

Step-by-step explanation:

The rational number is in the form of \frac{x}{y} , whereas x and y are the integers and q must not be equal to zero.

 Rational number is also a terminating or if not terminating it should be

re-occurring.

Considering the option B

726 is a rational number

\frac{7}{34} is also a rational number as per definition

20.209 is also a rational number

\sqrt{9}= 3, is also a rational number

Hence, option (B) is correct.

A circle is a collection of points all of which are on the circumference of the circle.  If you use algebra and (x-h)^2 + (y-k)^2 = r^2 and the info contained in the coordinates (x,y) of each city, you can find h, k and r.  Then r is the (equal) distance between each city and the center of the circle, where the new tower will be built.
