ANSWER

EXPLANATION
The given points are:
(1, 4), (2, 9), and (3, 16)
It is obvious that the function is not linear because there is no constant difference among the y-values.
We can however manipulate the y-values to quickly identify the function.



We can infer from the pattern that, the function is;

If $.72 per 1lb, then $x per 2.7lb, by using proportional property:
.72/1 = x/2.7 cross multiply
x = (.72)*(2.7) = $1.94
Answer:
Cylinder Volume = PI * radius^2 * height
Radius = Square Root [Volume / (PI * height)]
Radius = Square Root [ 134 / (3.14 * 7.1)]
Radius = 2.45103
Radius = 2.45
