I think I know what it forms - a cone!!
I'm guessing that the angles at the end are 10 degrees so that would make angle CAB equal 5 degrees.
Line AB would be the radius of the "upper cone".
Line BC is 12/2 or 6
tangent (A) = BC / AB
tangent (5) = 6 / AB
AB = 6 / tan(5)
AB = 6 / 0.087489
AB =

<span>
68.58 which is the radius of the "upper cone".</span></span></span>
Cone Volume = (PI * radius^2 * height) / 3
Cone Volume = (PI * 68.58 * 68.58 * 6) / 3
Cone Volume =

29,551
That is just the "upper cone volume. So, we multiply </span></span></span><span><span>

29,551 * 2
and get 59,102 which is the volume of the entire solid.

Basically, the problem is asking us to take 2.20, the length of AB, and work with it through the problem. Well, we are first told that the original polygon is reflected across the x-axis to form the polygon A'B'C'D'E'. This does nothing to the length of AB, so we can move onto the next given section. We are given that A'B'C'D'E' is dilated by a factor of 0.5 (1/2) to form the polygon LMNOP. Here, we will have to take 2.20, the original length, and divide it by 0.5, to get the length of LM. When we perform the operation, we get 1.10, or 1.1. Therefore, the length of LM is 1.10 units. Hope this helped and have a great day!
