Answer: It represents the area of the two circular sides ("lids")
Explanation:
Imagine you made a cylinder out of 3 pieces of paper. The cylinder can be decomposed into two circular shapes (radius r) and one rectangular piece with two side lengths: one is "h", the other has to be long enough to go around each of the disks, so it has to be 2*pi*r long.
So the term 2*pi*r*h is the area of the rectangular piece and pi*r^2 is the area of each of the "lids" Since there are two of those, the term 2*pi*r^2 represents the area of the bottom and top lids.

Answer:
First Step: separate x^2 from -16
Second Step: add -16/25 to the other side.
Step-by-step explanation:
x^2 - 16/25 = 0
^^ this might be easier if you separate x^2 and -16
<em>First Step-</em>
so rewrite the problem as x^2/25 -16/25 = 0
then...
<em>Second Step-</em>
add -16/25 to the other side. This makes it: x^2/25 = 16/25
<em>Continuation-</em>
Now, you can multiply 25 on both sides to cancel it out.
so you have x^2 = -16
