Answer:
container B requires more plastic to make.
Explanation:
Container A:
diameter- 7 cm
height- 122 cm
radius- 3.5 cm
calculating for the surface area
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
Container B:
diameter- 11 cm
height- 85 cm
radius- 5.5 cm
calculating for the surface area
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
Container B required more plastic to make
