<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>
Answer:
(we dont have the picture of the following ordered pairs, so I'll list all)
(4,1), (4,7), (1,4), (7,4)
Step-by-step explanation:
If the side lengths are 3 units, then you just add or subtract 3 to x or y in the 4 directions.
How you do this is using the formula speed = distance/time. So this is 100/5 which is 20 meters a second. Using the conversion factor (can google "20 meters per second is how many mile") 20 meters a second = 44.7 miles per hour.
In conclusion, the answer you're looking for is D. 44.7 miles per hour.
