Answer:
[tex]A=502.4\ \text{inches}^2[/tex]
Step-by-step explanation:
The radius of the ball, r = 2 inches
We need to find how many square inches of plastic does the company need to make 10 beach balls.
Let A be the area of 1 ball. Balls are in the form of spheres. The area of a sphere is given by :
[tex]A=4\pi r^2[/tex]
For 10 balls,
[tex]A=10\times 4\pi r^2\\\\=10\times 4 \times 3.14\times (2)^2\\\\=502.4\ \text{inches}^2[/tex]
Hence, the area of 10 beach balls is [tex]502.4\ \text{inches}^2[/tex].
