The correct option is: A. 80 cm³
Explanation
Diameter of the coin, 
cm.
So, the radius, 
cm.
As the coin is circular, so..
Area of each circular surface, 
cm²
Now for finding the amount of plastic for making each coin, we will find the Volume of each coin first.
As the thickness (
) of the coin is 0.5 cm, so Volume of each coin,
As you need to make a batch of 50 coins, so the total volume of 50 coins 
[Rounded up to the nearest multiple of 10 cm³]
So, the amount of plastic you will need for making a batch of 50 coins is 80 cubic centimeter.

Let r and r+18 be Dale's rate with and without traffic, respectively. Then
7r=5(r+18)
2r=90
r=45
7r=315
Dale lives 315 miles from the mountains
