I don't get how r2 + r1 = 2

help??

 

[Carrotsticks]

Notice the symmetry.

 

[Alkenes]

is cambridge enough for volumes??

Notice the symmetry.

 

[Alkenes]

yes and how does r2 - r1 = 2(1-y)6(1/2)

Notice the symmetry.

 

[Carrotsticks]

yes and how does r2 - r1 = 2(1-y)6(1/2)

They subbed in the equation found a few lines earlier.

And yes Cambridge is enough for volumes, but I suggest doing questions from a variety of books. Different authors have different question-styles.
