Deriving The Formula - Volume of Cone

[sakriyaronaldo]

dude u could have saved a lot of paper and ink .....if u'd used ur mouth

[sonac36]

This isn't a derivation.

[MrJamshaid3]

Excellent!



[PZX]

Use triple integral to derive it.. But I prefer this method because most of the ppl can't do integration well =p

what the heck is that juice of death?!?

[LittleMissMusicxx]

We watched this video and the one on pyramids in my math class...it's really helped me a lot! Thanks!

[jamesfelix303]

Ummmmmmm Im pretty sure that isnt water....

[gizmoshiloh]

@jamesfelix303 its food coloring.

[Blixv2]

Yeah, why don't you go ahead and have your 7th graders do some integration you freaking idiot. I mean, gosh, my 7th graders can do all sorts of legit calculus...oh, wait...they just need a simple demonstration as a base right now. I wonder if maybe this is what this person's goal was?

[webmastertool]

@Blixv2 i hope your not a teacher.

[JeanPlaisance]

@webmastertool Agreed. Nobody should be that immature, especially not a teacher.

[gvsfgdf]

@Blixv2 man when I has in grade 7 I was doing calculus of variations, analytic number theory, and renormalizing quantum electrodynamics as well as tapping megan fox and breakdancing :D

[Kanashto]

thank you

This does not prove the Volume of a Cone is 1/3BH.  This is only proof by example, which is not a valid proof technique. This only proves this works for that specific cone, rather than all cones. Try using 3-D graphs and interegrate repectively to get a general formula for the Volume.

[UserDudeOneAndAHalf]

obviously you were not paying attention the. the video is visual explanation stating that a cone has 1/3 the volume of a cylinder whose base has the same area and, has the same height as the cone. therefore since the volume of a cylinder is pi r^2 h so it is easily understood that the volume of a cone is 1/3 that formula ergo 1/3(pi r^2 h).

[Catty8D]

What does this mean ? I did not realize!

Can you explain to me in Portuguese?

is that I'm Portuguese ...

kisses

[bluesdjh]

Nice visual - can you post this on TeacherTube so that schools can use this with students - many schools block uTube. Thanks!

[KermitTheGreatest]

Hey guys, It's me, Karl!

[fategg21]

dude its eric :)

[OoohLaLaxx]

ummm.that isnt water

[StudDuck12345]

I agree.

oh, FYI--- I am StudDuck12345!'s daughter who has hacked onto his computer

bwa-haha!

this has really helped me understand that the volume of a cone is 1/3 of the area of the base times height (cylinder volume)

V=1/3Bh
