The diameter would be 6.67 mm
25.5 mm is.
The diameter is double the radius.
The diameter of a quarter is 24.26 mm. Circumference is pi* diameter. 24.26 mm * 3.14159=76.21 mm
The diameter of a quarter is 24.26 mm. Circumference is pi* diameter. 24.26 mm * 3.14159=76.21 mm

The diameter of a quarter is 24.26 mm. Circumference is pi* diameter. 24.26 mm * 3.14159=76.21 mm
The diameter of a quarter is 24.26 mm (0.955 in).
24.26 mm (0.955 US inches)
2.5 cm or 25 mm
US coins: Cent - 19.05 mm Nickel - 21.2 mm Dime - 17.9 mm Quarter - 24.3 mm Half - 30.1 mm Dollar (modern) - 26.5 mm
Regardless of what you happen to be measuring,10 mm = 1 centimeter18 mm = (18/10) = 1.8 centimeter
The measurement of 4 mm in diameter is equal to 0. 1575 inches in diameter. It is also equal to 0. 4 centimeters in diameter.

The first US quarters minted in 1796 ,1804,1805,1806 and 1807 were approximately 27.5 mm in diameter. Quarter minting was suspended until 1815 when the size was changed to 27 mm in diameter. This size quarter was minted until 1828 when quarter minting was again suspended. When it resumed again in 1831 the diameter had been changed to 24.3 mm and has been the standard for the US quarters until the present.
