Answer: 125.6 square inches of plastic is needed

Step-by-step explanation:

I can't open the images, sorry. But since the question is asking for square inches you know it wants the area. The area of a sphere (the beach ball) is Area= 3.14(radius)squared. So, the area of one beach ball is A= 3.14(2)squared or A= 12.56 square inches. Then you multiply it by 10 to get the area of all 10 beach balls, so the total amount of plastic needed is 125.6 square inches. Hope this helps!
