Answer 2

put the coefficients in order from biggest to smallest
and that would be your bottom to top order
so then 1b , 1/2 b , 1/4 b in that order is bottom to top.
so 1/2 b is the middle
and since b is the circumference of the base, 1/2 is half of that

Answer 3

So, \(b\) is the circumference of the bottom tier. Everything else is written in terms of it. That means \(\frac{1}{2}b\) means half the circumference of the bottom tier.

Answer 4

so the answer is A
