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).
18 inches
The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.
The diameter is double the radius of a circle. So you get 5 inches for the diameter.
The diameter of a circle is twice the radius. A radius is half of a diameter.
The radius of a circle is one-half of the circle's diameter. So if the radius is 12 inches, the diameter is 24 inches.
the diameter of a circle with the radius of 9m is 18m
the radius of a circle is half the diameter, so half of 1.8 is .9. The radius is .9km.
The diameter is always double the radius so in this case, it is 18cm
9
The answer is 9
Diameter = 2*9 = 18 units
9 mm
9'
R=D/2. If the diameter of a circle is 18 inches, the radius is 9 inches. Radius = 1/2 diameter or 9"
Diameter = 2 x radius = 9 meters
Radius is half the diameter. 18 / 2 = 9 Answer: 9.0 cm
r= 9 so diameter is 2x the radius =18 cm
