Question

Kaitlyn and Hakim each bought a tube

Answer 1

Answer:

container B requires more plastic to make.

Step-by-step 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
