False because it is the other way around in that if the diameter is 18 yards then the radius is 18/2 equals 9 yards.
No. "Then" its diameter is 9 yards.
Diameter = 2 x radius = 18 mm .

If the diameter of a circle is 18 inches then its radius is 18/2 = 9 inches
r= 9 so diameter is 2x the radius =18 cm
The diameter is always double the radius so in this case, it is 18cm
The diameter of a circle is twice the radius. A circle with a radius of 9 would have a diameter of 18. (9*2=18).
Radius is half the diameter. 18 is the answer.
It's 18 cm. The radius is half the diameter of a circle. Half 36 cm is 18 cm.
Radius is half the diameter. 36/2=18
It is 18 centimeters because your radius is exactly half of the diameter in any circle
Diameter = 2 x radius = 18 mm .

If the diameter of a circle is 18 inches then its radius is 18/2 = 9 inches
radius = 18/2 = 9 cm
Diameter is twice the radius, so 18 feet.
r= 9 so diameter is 2x the radius =18 cm
Radius is half the diameter. 18 / 2 = 9 Answer: 9.0 cm
