MakcuM [25]

Answer:

Approximately the volume of cone-shaped container is 393 in³.

Step-by-step explanation:

Given:

A company makes a cone-shaped container with a height of 15 in.

The area of its base is about 78.8 in².

Now, to get the cone-shaped container volume.

So, we find the radius first by using formula:

Let the radius be $r.$

(Using the value π = 3.14)

$A_{B}=78.8\ in^2.$

$A_{B}=\pi r^2$

$78.8=3.14\times r^2$

Dividing both sides by 3.14 we get:

$25.09=r^2$

Using square root on both sides we get:

$5.00=r$

$r=5\ in.$

Thus, the radius ( $r$ ) = 5 in.

The height ( $h$ ) = 15 in.

Now, to get the volume of the cone-shaped container we put formula:

$Volume=\pi r^2\frac{h}{3}$

$Volume=3.14\times 5^2\times \frac{15}{3} \\\\Volume=3.14\times 25\times 5\\\\Volume=392.50\ in^3.$

Therefore, approximately the volume of the cone-shaped container is 393 in³.

Magdeline wants to know if the number of words on a page in her art book is generally more than the number of words on a page in

navik [9.2K]

The deviation σ in the art book =15.4, the σ in the Science =7.9

Consequently the art book has data further away from the mean when compared to the science book. It will be difficult to have a valid inference.
No, because there is a lot of variability in the art book data

Find x (4,12), (x,18); slope=3

vodomira [7]

(y - yo) = m.(x - xo)

We have the points (4, 12) and (x, 18) with slope of 3.

(18 - 12) = 3.(x - 4)

6 = 3x - 12

3x = 6 + 12

3x = 18

x = 18/3

x = 6
