Kim has a metal casting company which makes commemorative coins. she has 0.12 cubic meters of silver which she needs to make into 1.07e5 coins of thickness 2 mm. if she uses all of the silver, what is the diameter in centimeters of each coin

The coin has a diameter of 2.67 cm

Explanation:

First, we need to find the volume of each coin by dividing the total volume of silver by the number of coins. We have also to do a conversion of units in terms of centimeters as follows:

Then, we define the coin as a tiny cilinder to determine its diameter. In that order we use the cilinder's volumen equation as follows:

Finally, we know that the diameter is twice the radius, therefore the diameter of each coin is 2.67 cm.
