Nineteen millimeters.
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 US penny is 1.9 centimeters, or 19 millimeters.
Meter.... or more likely millimeters
A US quarter has a diameter equal to 0.00002426 km

A U.S. dime is 17.91 millimeters in diamater, which is 0.00001791 kilometers.
The diameter of a U.S. penny is 19.05 millimeters, which is equivalent to 0.75 inches in customary units.
The diameter of a circle is twice the length of its radius. If the radius is 12 millimeters, the diameter would be 2 times 12 millimeters, which equals 24 millimeters.
Assuming you mean a quarter US dollar, it is 2.426 cm.
