<h3>
Answer: 75.36 square feet</h3>
Your teacher may want you to type the number only.
==========================================================
Work Shown:
SA = surface area of a cylinder
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*3.14*2^2 + 2*3.14*2*4
SA = 75.36
The surface area is roughly 75.36 square feet.

Answer:
72 = 30%
Step-by-step explanation:
240 = 100%
24 = 10%
12 = 5%
2.4 = 1%
72 / 24 = 3
72 = 30%
Let me know if I got it wrong :)
<span>Inflection points are where the function changes concavity. Since concave up corresponds to a positive second derivative and concave down corresponds to a negative second derivative, then when the function changes from concave up to concave down (or vise versa) the second derivative must equal zero at that point. So the second derivative must equal zero to be an inflection point. But don't get excited yet. You have to make sure that the concavity actually changes at that point.</span>
