Re: O is the center of the two circles and OX = XY = 1 [#permalink]
For this question, you are given that O is the center of both circles and OX = XY = 1.
With the givens, this means that OY = 2, which is important since the question is asking for circumferences, which requires radii in the calculation.

Quantity A:$$\frac{2pi*OY}{2}$$
Quantity B:$$2pi*OX$$

Quantity A:$$pi*OY$$
Quantity B:$$2pi*OX$$

Here we substitute OY for 2 and OX for 1

Quantity A:$$2pi$$
Quantity B:$$2pi$$

Quantity A is equivalent to Quantity B.
