Answer:
Approximately the volume of cone-shaped container is <u>393 in³</u>.
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 
<u><em>(Using the value π = 3.14)</em></u>
<em>Dividing both sides by 3.14 we get:</em>
<em />
<em />
<em>Using square root on both sides we get:</em>
Thus, the radius (
) = 5 in.
<u>The height (</u>
<u>) = 15 in.</u>
Now, to get the volume of the cone-shaped container we put formula:
Therefore, approximately the volume of the cone-shaped container is 393 in³.
Bear in mind that the area of a "parallelogram" is base * height.
notice the picture, the front and back parallelograms, have an altitude/height of 3 cm, and a base of 8 cm, so the area of one of those two is 3*8.
as far as the left and right parallelograms, they have a base of 7 cm, but the altitude is also 3 cm, so the area of one of those is 3 *7.
bear in mind the altitude/height is the distance from the base to the top, and in this case is just 3 cm.
anyway, you have 4 parallelograms, get the area of each, add them up, and that's the surface area of the figure.
2(3*8) + 2(3*7).
Answer:
x <= -42.5
Step-by-step explanation:
65 - 2x >= 150
-2x >= 150 - 65
-2x >= 85
2x <= -85
x <= -85/2
x <= -42.5
