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
The answer is 9
9 mm
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).
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
The answer is 9
9
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
