# Medal

Calculate the approximate weight of the gold Olympics medal, if its diameter is 8 cm and a thickness 6 mm. The density of gold find out in the tables or on the Internet.

Result

m =  582.07 g

#### Solution:

$\rho = 19.30 \ g·cm^{−3} \ \\ m = V \rho = \pi r^2 h \rho = \pi \cdot (8/2)^2 \cdot (6/10) \cdot 19.3 = 582.07 \ \text{ g }$
