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.
The pattern is increasing by 10 then a ding 1 to the next number. Hope this helps! :)
A = 289
That's the side s squared,
s² = 289
s = 17
In a square the perimeter is the sum of four equal sides
p = s + s + s + s = 4s = 4(17) = 68
Answer: 68 feet
Answer:
7 jars per box
Step-by-step explanation:
He now has 41 jars. How many did he have before his teacher gave him 6?
Well, 41-6=35. He had 35 jars before his teacher gave him more.
It says there was an equal amount of jars in each box. There are 5 boxes. Divide the total amount of jars (35) by the amount of boxes to find out how many jars are in each box.
35 jars / 5 boxes = 7 jars / box
