Answer:
WHat do you mean
Step-by-step explanation:
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.
I hope this helps..... ;)
G(x) = ax^2
y = ax^2
16 = a1^2
a = 16
Therefore, g(x) = 16x^2
