attachment

anonymous · Answer

does that help?

diyadiya · Answer

Yes.!
So what do you think is the answer?

diyadiya · Answer

Circle 4 is a great circle of the sphere.
 
I guess thats the answer.

diyadiya · Answer

Let me clarify

anonymous · Answer

i was about to say one of the last two aha

diyadiya · Answer

But i'm not sure if 2 & 3 are concentric or not

apoorvk · Answer

great circle is the largest circle that a sphere can accomodate, @cbrusoe . so what do you think now?

apoorvk · Answer

@Diyadiya - do 2 and 3 have a common centre? think-o!

diyadiya · Answer

But aren't they inside a sphere ?

apoorvk · Answer

and @cbrusoe I am sorry, you had called me to an earlier question, but the image link didn't work there as well - you "www.flvs..." links don't work it seems.

anonymous · Answer

i would think it is circle 4 then because it seems like it is the largest circle within the sphere

apoorvk · Answer

Doesn't matter if they are inside a sphere or an ellipse or a cube or a telephone - common centers or not? let's not think about the axis of the centers - consider only the center.

anonymous · Answer

its ok i dont remember which question it was but i think i got it i'll start attaching them for now on

diyadiya · Answer

OH YEAH! i got confused with the axis

apoorvk · Answer

yeah, cbrusoe, you are right! - the great circle inside a sphere is analogous to the diameter of a circle.

diyadiya · Answer

@cbrusoe Sorry for the confusion & Thanks @apoorvk

apoorvk · Answer

lol, no problem - i myself thought so for a moment.

And don't thank me everytime for petty reasons :P
