The diameter is always double the radius so in this case, it is 18cm

Is the diameter of a circle bigger or smaller then the radius?
The diameter is twice as long as the radius. d = 2r The diameter is basically a line through the center of a circle while a radius is from the center to the circumference of a circle.
If the diameter of a circle is 12 cm long how long is the radius?
The radius would be 6 cm because the diameter is 2 times bigger than the radius.
Radius of circle is 16 inches how long is diameter?
32"
What is the diameter of a circle if the radius is 6 cm?
12 cm A diameter is twice as long as the radius of a circle. D = 2r D = 2(6cm) = 12cm
What is the area of a circle if it has a diameter which is 18 feet long?
The area of a circle is equal to πr2 where π (pi) is equal to approximately 3.142 and r represents the radius of the circle. Because the question gives you the diameter and not the radius you have to use the measurement of the diameter to calculate the radius. Remember that the radius is equal to half the diameter. So if the diameter is equal to 18 feet, then the radius of this particular circle is equal to 9 feet. Plugging this into our equation for area we get: area = π(92) area = 3.142(81) area = about 254.5 ft2 (don't forget that the answer is in squared feet not just feet)
If a circle has radius that is 12 feet how long is the circles diameter?
Since radius is half of a diameter, therefore 12 x 2 = 24
If the diameter of a circle is 12 inches how long is the radius?
Diameter of a circle is defined as twice the radius. So if diameter is 12, the radius is 6.
If the radius of a circle is 5cm long what's it diameter?
The diameter is twice the radius.
How long is the diameter if the radius is 70 cm?
The diameter of a circle with radius 70 is 140.
Is the diameter of a circle bigger or smaller then the radius?
The diameter is twice as long as the radius. d = 2r The diameter is basically a line through the center of a circle while a radius is from the center to the circumference of a circle.
Is the diameter of a circle 2 x radius?
Yes. The radius is from the centre to the edge of the circle. Therefore, 2xr is twice as long and is the diameter of the circle.
What is diameter of a circle measures 16in how long is the radius?
diameter=2*radius 16 in = 2*radius 8 in = radius
If a circle has a radius of 8 cm long how long is the circle's diameter?
16cm
If the radius of a circle is thirteen how long is the diameter?
26
What is the diameter of a circle with a 5cm long radius?
10cm
If a radius is 15 inches long, how long is a diameter?
The radius of a circle is half the diameter, thus your measurement is 30 inches
If the diameter of a circle is 12 cm long how long is the radius?
The radius would be 6 cm because the diameter is 2 times bigger than the radius.
