Comment on Circles
Thank you for your prompt
I could not even understand what is being asked
https://gmatclub.com/forum/the-center-of-a-circle-is-5-2-5-7-is-outside-the-circle-189027.html
Possible values of r? One radius for a circle right?

I didn't draw out a figure like you did in the approach. The way I approached this was to determine if both x and y were points that were in Q2.
So statement 1 and 2 by itself were clearly insufficient. Combined, they still gave the information that both x and y could lie on the negative and positive sides on the plane.
Is this approach ok? Also, if the statements showed that x and y could be 0 (point of origin) and nothing more, then I'm guessing this doesn't count as it doesn't tell us if the line passes through Q2

That approach works.
Since the circle does not pass through the origin, x and y cannot both equal zero.

But if the circle did pass
The point (0,0) is not in any
The point (0,0) is not in any of the quadrants. That is, we cannot say that (0,0) is in Quadrant 2.
That said, I'm pretty sure the test-makers won't create a question that relies solely on that fact.

Hi Brent,
Could you please explain the solution for this problem?
The outer dimensions of a closed rectangular cardboard box are 8 centimeters by 10 centimeters by 12 centimeters, and the six sides of the box are uniformly 1/2 centimeter thick. A closed canister in the shape of a right circular cylinder is to be placed inside the box so that it stands upright when the box rests on one of its sides. Of all such canisters that would fit, what is the outer radius, in centimeters, of the canister that occupies the maximum volume?
A. 3.5
B. 4
C. 4.5
D. 5
E. 5.5
Thanks
