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 radius of a circle is half of its diameter. Therefore, if the diameter of the circle is 60 inches, the radius would be half of 60, which is 30 inches. The formula to find the radius from the diameter is: radius = diameter / 2.
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 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
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
