Answer:
1D 2B 3A
Step-by-step explanation:
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 =

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 =

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

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

Answer:
1
Step-by-step explanation:
Answer:
i think -1/26
Step-by-step explanation:
(y2 - y1) / (x2 - x1)
(-15+16) /(-7-19)
1/-26
In this case the answer would be the last option
because it is shrunk by 2/3 on just the x side
D is the only one who has that first transformation
