What is the radius of a quarter?

Answer 1

It's 12, I'm almost positive.

Because I found the weight to be 7.5 grams, and the volume to be .625 ml's.

So do the math and you come up with 12.

12 g/ml = 12(g/ml)*(1/1000)(kg/g)*1(ml/cm^3)*(100^3/1)*(cm^3/m^3) = 12,000 kg/m^3

Answer 2

The radius of a quarter is approximately 0.5 inches or 12.7 millimeters.

Answer 3

diameter 0.955 inches (24.26 mm)

radius is half of that

Answer 4

im not quite sure im only 12
