If the diameter of a circle is 18 inches then its radius is 18/2 = 9 inches

Since your circle has a diameter of 9 feet (the definition of a "9 by 9" circle), the radius is half of that distance. In this case, your radius is 4.5 feet or 54 inches.

the diameter of a circle with the radius of 9m is 18m

The area of a circle with a diameter of 9 inches is: 63.62 square inches.

the radius of a circle is half the diameter, so half of 1.8 is .9. The radius is .9km.
