Hi! Trying to understand the explanation here-- I know we have a 5, 12, 13 triangle. One case is the diameter is the 13, in which case radius is 6.5
The solution video mentioned it’s a possibility that the 12 is diameter, and then 13 is just a chord in the circle. I’m a little confused how this could be the case-- isn’t the diameter the longest chord in the circle? So how could 12 be the diameter but 13 be a chord? Essentially, I’m confused why the answer isn’t “Quantity A is bigger” because the minimum radius is 6.5.
Thank you!!
