Assuming that r is the radius of the coin and h is its height, then πr^2*h represents the volume of the coin (assuming that the coin is perfectly cylindrical).
The density of a material is its mass divided by its volume. Therefore, the required density is:
d = m/V
= (14.1 g)/(1.69 x 10^-3 m^3)
≈ 8343 g/m^3.
I hope this helps!
