It says a cylinder has one curved face and two congruent circular bases.

they removed it from CCSS. Makes one question who would be the top dog who would end this uncertainty and debate by designating just one definition. Is anyone sailing this ship?

A quick google search brings up the answer of two faces per cone (a wrapped face and a circular face) but I did find a site saying zero for reasons PP mentioned!

Old discussion: http://www.proteacher.net/discussion...ad.php?t=34076

I think that "less than 3" covers it for a cone and "less than 4" covers it for a cylinder!

Sorry I was no help. Now I am curious to find the correct answer as well.

thanks for the help!!

I was hoping common core had addressed it somewhere. Our math books (HM in fourth grade) state that the cylinder, cone and sphere have 0 faces because faces have to be polygons. So the debate continues.....

Although it doesn't really answer the "How many faces" question, it ends the need to use common language.

have an answer for the on going question: How many faces on a cylinder/cone?? I know it has been discussed before, but I was hoping common core might have addressed it somewhere and I just can't find it. We actually contacted the district guru and got some weird gibberish answer trying to avoid a definite answer. I was hoping that I could take the common core answer in and put an end to the debate. TIA
