A construction worker is filling a container in the shape of a right circular cylinder with cement. the container has a base dia

kirza4 [7]

The volume of this container is 5990 feet³.

<h3>How to calculate the volume?</h3>

Volume of a cylinder = πr²h

π = 3.14

r = radius = 17.5/2 = 8.75

h = 24.5

The volume will be:

= πr²h

= 3.14 × 8.75² × 24.5

= 5990 ft³

Therefore, the volume of this container is 5990 feet³.

Which models show 40%? Check all that apply. A model with 4 shaded sections and 6 unshaded sections. A model with 40 shaded sect

Amanda [17]

Answer:

A model with 4 shaded sections and 6 unshaded sections.

A model with 40 shaded sections and 60 unshaded sections.

Step-by-step explanation:

Required:

Which models shows 40%

(a) 4 shaded and 6 unshaded

First, we calculate the total sections

$Total = 4 + 6$

$Total = 10$

The percentage of the shaded section is:

$Shaded = \frac{4}{10} * 100\%$

$Shaded = 0.4 * 100\%$

$Shaded = 40\%$

(b) 40 shaded and 60 unshaded

First, we calculate the total sections

$Total = 40 + 60$

$Total = 100$

The percentage of the shaded section is:

$Shaded = \frac{40}{100} * 100\%$

$Shaded = 0.4 * 100\%$

$Shaded = 40\%$

(c) 2 shaded and 8 unshaded

First, we calculate the total sections

$Total = 2 + 8$

$Total = 10$

The percentage of the shaded section is:

$Shaded = \frac{2}{10} * 100\%$

$Shaded = 0.2 * 100\%$

$Shaded = 20\%$

<em>Hence, (a) and (b) shows 40%</em>

Given the following coordinates complete the glide reflection transformation.

Romashka [77]

Answer:

$A" = (7,-2)$

$B" = (10,0)$

$C"= (12,-3)$

Step-by-step explanation:

Given

$A = (4,2)$

$B = (7,0)$

$C =(9,3)$

a: Reflect over x-axis

The rule of this is:

$(x,y) \to (x,-y)$

So, we have:

$A' = (4,-2)$

$B' = (7,0)$

$C' = (9,-3)$

b: Shift 3 units left

The rule of this is:

$(x,y) \to (x+3,y)$

So, we have:

$A" = (4+3,-2)$

$A" = (7,-2)$

$B" = (7+3,0)$

$B" = (10,0)$

$C"= (9+3,-3)$

$C"= (12,-3)$
