A quarter of a metre is 0.25 m = 250 mm. There are 1/250 of them in 1 millimetre.
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
Diameter: 24.26 mm Circumference: 76.215 mm
To calculate the radius of a quarter in millimeters, you first need to know the diameter of the quarter. A U.S. quarter has a diameter of 24.26 mm. The radius is half of the diameter, so you divide 24.26 mm by 2, resulting in a radius of approximately 12.13 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)
A U.S. quarter has a diameter of 24.26 mm. Its thickness is approximately 1.95 mm. This size makes it one of the larger coins in circulation in the United States.
Regardless of what you happen to be measuring,10 mm = 1 centimeter18 mm = (18/10) = 1.8 centimeter
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
2.5 cm or 25 mm
An 8 mm circle has a diameter of approximately 0.31 inches, as 1 mm is equivalent to about 0.03937 inches. To visualize, an 8 mm circle is smaller than a standard American quarter, which has a diameter of about 0.95 inches. Therefore, the 8 mm circle is quite compact, roughly one-third the diameter of the quarter.
