Answer:
The length of diagonal PS and diagonal P'S' are in the ratio 1:3.
Step-by-step explanation:
Comparing the coordinates of the vertices,
P(0, -3)→P'(0, -9); Q(3, -2)→Q'(9, -6); R(3, 1)→R'(9, 3); S(0, 2)→S'(0, 6); T(-2, 0)→T'(-6, 0)
We can see that the pre-image points have been multiplied by a scale factor of 3. This means comparing the pre-image sides to the image sides, the ratio is 1:3. However, we must compare corresponding sides; the only choice comparing corresponding sides with a ratio of 1:3 is PS to P'S'.

It's unclear what the planes are supposed to be, so I'll take 
and 
with 
.
The cross sections are disks with diameter 
, so each disk of thickness 
has a volume of
Then taking infinitesimally thin disks, we find the solid has a volume of
Since
and
it follows that the volume is
I know that in some schools if your teachers feel you have what it takes to be in a higher grade level they might give you a choice to take a placement test to determine whether or not your ready to move up .
