Question

Difficult Level (?) - Ok. So apparently you can determine a direct equation from seemingly indirect values for x & y with Proportionality. How would you go about doing this? (ill post an example)

Answer 1

Ok. So when r radius is (0.5, 1, 1.5 and 2) V volume is (0.5, 4.2, 14.1 and 33.5). Doesn't seem direct, right, until you rearrange it to be pi*(4/3) * r^3

Answer 2

How is this process determined? How do you do this with other apparently indirect, random numbers?
