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! :)

Answer:
Step-by-step explanation:
Part A:
-mk-120 > 95
-mk > 215
Divide both sides by -k
Since we are dividing by a negative, the inequality sign flips
m < 215/-k
Part B:
2c-9fb = 45
Subtract 2c from both sides
-9fb = 45-2c
Divide both sides by -9b
f = (45-2c) / -9b
Please let me know if this helps :)!
