slant height of conethis ques. is based upon vol. and surface area. friendship is tan 90°. #2 20131011 23:03:26
Re: slant height of conehi niharika_kumar and I cannot match any of these answers yet so I need more information if I'm to give you any more help. Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #3 20131012 09:57:43

Re: slant height of conethnx bob and anonimystefy but there is nothing extra info. given apart frm what i mentioned above . And i tried but couldn't figure it out. friendship is tan 90°. #5 20131012 19:16:38
Re: slant height of conehi niharika_kumar using my second diagram. That looks quite a bit like answer b except r2 rather than r1. But for r1  r2 to be positive r1 must be the radius of the larger base, so I'm still puzzled. anonimnystefy: It comes to the same thing; either way you get an expression with r1  r2.

Re: slant height of conei completely agree with u bob , i think the options printed there are wrong. friendship is tan 90°. #7 20131013 01:44:33
Re: slant height of cone
Aren't we looking for L+y, not just y?

Re: slant height of coneWell, L+y is the slant height of the whole cone, right?
