Any point with coordinates (x, y) reflected across the y-axis is going to have the opposite x value that it did before.
You should be able to find the coordinates yourself for part a. (you didn't provide the original ones so I can't help you there)
Here is the "rule" for a reflection across the y-axis:
And when we go 1 unit to the right and 2 down, that's the same as
Combining those into one rule is pretty simple, Use our result for the first in the second and we would get
, so the rule is
.
Part A is asking for the coordinates after the reflection (x, y) ⇒ (-x, y).
Part C is asking for the coordinates after the full translation ⇒ (-x+1, y-2)

Answer:
Radius = 12 cm
Step-by-step explanation:
Given:
Volume of the cylinder is, cm³
Height of the cylinder, cm
Let the radius be
Using the formula for volume of cylinder,
Plug in 3165.12 for , 7 for
and solve for
.
Therefore, the radius of the cylinder is nearly 12 cm.
