Answer:
Not proportional.
Step-by-step explanation:
A proportional relationship is a relationship which crosses through the origin (0,0) and which has a proportional constant. We can determine this either by finding (0,0) where x=0 and y=0 in the table or by dividing y/x. None of the tables contain (0,0) so we will divide y by x. We are looking for a table which when each y is divided by its x we have the same constant appearing.
Though it has a point at the origin, these fractions are not equal. This is not proportional.

A cell has a radius: r = 3 nmThe surface area of a cell:A = 4 r² π = 4 · 3² π = 4 · 9 π = 36 π nm²The volume of a cell:V = 4/3 r³ π = 4/3 · 3³ π = 4 · 9 π = 36 π nm³Answer: The surface area is 36 π nm² and the volume is 36 π nm³.
Luckily 22 is half of 44 so this is not too hard.
If 44 is 44% 100 and 22 is half of 44, we can just use this info and find half of 100 to give us our answer.
100/2=50
So 22 is 44% of 50
I’m sure the answer is x=19
