A 12 mm circle has a diameter of 12 millimeters, which is slightly less than half an inch (approximately 0.47 inches). The radius, which is half the diameter, is 6 mm. In terms of area, the circle has an area of about 113.1 square millimeters. This size is comparable to the diameter of a large button or a small coin.
The radius of a circle is always half of the distance of the diameter. If you have a 24 mm diameter - then the radius would be 12 mm.
Th American cent is 19 mm in diameter.
d = 2r = 12 mm
An 18 mm measurement is equivalent to approximately 0.71 inches. To visualize it, 18 mm is slightly larger than a US quarter, which has a diameter of about 24.26 mm. In terms of circumference, if you were to create a circle with a diameter of 18 mm, its circumference would be about 56.5 mm or 2.22 inches.
The answer will depend on what the 12 mm measures. If the object is 12 mm in diameter, it is 37.7 mm around.

24 mm. The diameter is twice the radius.
AWG # 12 is 2.053 mm in diameter.
The radius of a circle is always half of the distance of the diameter. If you have a 24 mm diameter - then the radius would be 12 mm.
Th American cent is 19 mm in diameter.

The spinal canal is usually more than 0.5 in (12 mm) in diameter. A smaller diameter indicates stenosis. The diameter of the cervical spine ranges is 0.6-1 in (15-12 mm). Any opening under 0.5 in (13 mm)in diameter is considered evidence of stenosis.
The circumference of a circle with a diameter of 55 mm is: 172.8 mm
Twelve inches is a length. It can be a diameter, but if it is a diameter, you would simply say 'The circle is 12 inches diameter'. So; how big is it - it is 12 inches.
A human egg cell is about 0.12 mm in diameter.
