<h2>Answer:</h2>

<h3>container B requires more plastic to make.</h3>

<h2>Step-by-step explanation:</h2>

Container A:

diameter- 7 cm

height- 122 cm

radius- 3.5 cm

<h3>calculating for the surface area</h3>

SA=2×π×r×r+2×π×r×h

SA=2(3.14)(3.5)(3.5)+2(3.14)(3.5)(122)

SA=76.93+2681.56

SA=2758.49 cm^2

<h3>Container B:</h3>

diameter- 11 cm

height- 85 cm

radius- 5.5 cm

<h3>calculating for the surface area</h3>

SA=2×π×r×r+2×π×r×h

SA=2(3.14)(5.5)(5.5)+2(3.14)(5.5)(85)

SA=189.97+2935.90

SA=3125.87 cm^2

<h3>Container B required more plastic to make</h3>

Solve through substitution<br><br> –3x–8y=20<br><br> y=5x+19<br><br> Point of intersection, please
Sedaia [141]

Answer:

(-4, -1)

Step-by-step explanation:

-3x - 8y = 20; y = 5x + 19

y = 5x + 19; -3x - 8y = 20

y = 5x + 19

-3x - 8y = 20

-3x - 8(5x + 19) = 20

-43x - 152 = 20

-43x - 152 + 152 = 20 + 152

-43x = 172

-43x / -43 = 172 / -43

x = -4

y = 5x + 19

y = (5)(-4) + 19

y = -1
