Answer:
I think either A or B. not sure though
Step-by-step explanation:
Hello!
The area of a cylinder formula- Area = Pi * radius squared * height
<span>In this case we are looking for height (altitude) </span>
<span>plug in our known values </span>
<span>500 = area </span>
<span>4 = radius </span>
<span>Pi ~ 3.141592654 </span>
<span>to find height... </span>
<span>500 = 3.141592654 * (4)^2 * height </span>
<span>500 = 3.14 * 16 * height </span>
<span>500 = 50.26 * height </span>
<span>divide both sides by 50.26.. </span>
<span>9.947 = height
</span>
<span>9.95 is the Correct Answer ( letter C)
</span>
Hope this Helps! Have A Wonderful Day! :)

explanation is I remember having this question and studying this bad in middle school :)
Using the volume of the spherical balloon, it is found that it will take 24 hours for the balloon to become completely empty.
<h3>What is the volume of a sphere?</h3>
The volume of a sphere of radius r is given by:
Aspherical balloon has a radius of 6 feet, hence the volume is:
It has already lost 20% of it's air, and air is leaking out of the balloon at a rate of 30 cubic feet per minute, hence the volume after t minutes is given by:
It will be completely empty when:
Rounding, it will take 24 hours for the balloon to become completely empty.

Let us say that h is the height of the guardrail.
Therefore the inequality equation that we can generate from this scenario is:
| h – 106 | = ± 7
There are two ways to solve this, either the equation is
positive or negative.
When the equation is positive, therefore:
| h – 106 | = 7
h = 7 + 106 = 113 cm
When the equation is negative, therefore:
| h – 106 | = - 7
h = -7 + 106 = 99 cm
So the height must be 99 cm to 113 cm
