As part of a new advertising campaign, a beverage company wants to increase the dimensions of their cans by a multiple of 1.10.
Margaret [11]

Answer:

Question 1 ) Difference of Volume = 112.25 cm³

Question 2) Volume = 6400π feet³

Step-by-step explanation:

<h3>As part of a new advertising campaign, a beverage company wants to increase the dimensions of their cans by a multiple of 1.10. If the cans are currently 12 cm tall, 6 cm in diameter, and have a volume of 339.12 cm3, how much more will the new cans hold? Use 3.14 for π and round your answer to the nearest hundredth.</h3>

Diameter = 6 cm

Radius = 3 cm

Height = 12 cm

If we increase the dimension by 1.10, new dimesnions are:

Radius = 3 · 1.1 = 3.3 cm

Height = 12 · 1.1 = 13.2 cm

Volume = (Area)(Height) = (πr²)(Height)

Volume = (π)(3.3²)(13.2)

Volume = 451.37 cm³

Difference of Volume = 451.37 cm³ - 339.12 cm³

Difference of Volume = 112.25 cm³

<h3>The circumference of a redwood tree trunk is 16π ft, and it is 100 ft tall. What is the approximate volume of the redwood tree trunk? </h3>

Circumference = 2πr = 16π = 2π(8) feet

Radius = 8 feet

Volume = Volume = (Area)(Height) = (πr²)(Height)

Volume = (π)((8²)(100)

Volume = 6400π feet³

All the cubes below have a different image on each side.
-BARSIC- [3]

Answer:

  • <u>Figure G</u>

Explanation:

The figure labeled A cannot be because the cross and the line are not oriented in  the same relative position as in X.

The figure labeled B cannot be because the line and the the image with the three lines are not oriented in the same relative position as in X.

You cannot tell about the figures labeled C because you do not see the images of the cross and the line.

The figure labeled E cannot be because the image with the three lines is not oriented in the same relative positiion with respect to the other two as in X.

You cannot tell about the figure labeled F because the image of the cross and with the three lines are not shown.

The figure labeled G is correct: you can just rotate the cube labeled X 90 degrees counterclockwise about a vertical axis that passes through the center of the cube and get the cube labeled G.
