Suppose your metal sample is hammered into the shape of a thin coin with a diameter of 8.62 cm. Determine the thickness (in mm) of this metal sheet. Use the measured metal mass and true denisty of your metal for this calculation. measured metal mass: 83.956 g
true density: 8.90 g/cm3

The thickness of the metal sheet is 0.162 centimeters.

Explanation:

If mass within the coin is uniformly distributed, then the density (), measured in grams per cubic centimeter, can be represented by the following formula:

(1)

Where:

- Mass, measured in grams.

- Diameter, measured in centimeters.

- Thickness, measured in centimeters.

If we know that , and , then the thickness of the coin is:

The thickness of the metal sheet is 0.162 centimeters.
