Surface Area of a Cylinder

[TheSparrowBlack]

I am the younger sister of the user this is my millionth try finding help for math,this helps a little bit but its still hard :( thanx for da help I get it a little more now!:D

[EPICOSITY83]

thnx for helping me with my homework

[ColonJimmy]

wat about the lenght?

[dem0niclullab13z]

BabelMath, Sir, I am eternally grateful. This was an AMAZING demonstration explaining very clearly how to find the S.A. of a cylinder. If I have any more trouble with math, I'll be sure to check your channel. :)

[gpgsingh12]

sir im really lost like seriously

[MrAlainchristian]

I got 100 on my test I wish u were my math teacher thank you very much for helping

[defqongabberhan]

[crazymonkey86056]

i think im gonna go CRAZY

[IDontHateOnCars]

I'm confused my homwork says 2B+P(h) which is height. What is P????? I guess perimeter. It seems like my teacher does half what this guy did. I just don't pay attention most of the time.

[BossMode99]

im still gonna fail :(

[TieFreaty]

@BossMode99 watch it till you get it and just try your hardest , i suck so badly at ,math... i hate it

[naomijh97]

[kev4069]

Thank you so much, it really helps!

[XxLoveIceXx]

the writing is too small. i cant even see. tht spoils everything :/

[TheJDCooper1997]

youtube people are much better then my actual teachers

[NickMouritsen]

@TheJDCooper1997 He is a teacher..

[dem0niclullab13z]

@TheJDCooper1997 I agree. v.v my teachers try to make everything sound extra confusing so we think they are smart and gain respect for them, when in reality I'd have so much respect for them if they actually taught me how to solve a problem without me having to ask the interwebs.

[JUNO8820]

what grade would learn this stuff? i am eigth grade and i am just wondering



[imadude55]

@JUNO8820 Sophmore year, or when ever you take geometry. usualy after Algebra 1

[leaheclipse10]

THANK YOU SO MUCH!!!!!:D

[antfrapalm]

Thank you so much, this helped!

[ronal91027]

i got the rong anser on my homework!!!!

[KidConanlover]

im in 6th grade advanced math and  i get it now! thanks!

soooooo much better than text book!

[video2play4ever]

@KidConanlover Same lol. I had homework and I didn't know the formula and didn't understand the text.

[carlyrok101]

im in 6th grade but in advanced math and even i didnt get this so thankful for this video wouldnt you agree?!

[elijah212100]

Yea you are the best teacher.. You explain it soo well

[kevinljm]

Thank you!! Best teacher EVAR!!!!

[brownienikky]

you made it seem so easy

[brownienikky]

thanks this helped alot!!!!!!!!!!!

[LifesBadHabit]

why dnt you do it with pi because we actually cnt figure out just put pi in a test we have to the exact answer

[luciferXlilith]

thank you!!! i missed half of grade 8 so i didnt get this AT ALL!!! thank you!!

--life saver!!--

[amberview30]

i got 534.07. Is something wrong with my calculator?

[TANKKER5]

i got my grade fom B to A from this

[COCKENERGY]

Thanks buddy! I removed several patches of hair before I found this !

[JonasBrothersVideos4]

To clear things up, you multiply the radius by 2 to get the circumference???

[jjjooorrrjjjooorrr]

@JonasBrothersVideos4 Yes you multiply the radius by 2 and also by Pi.

[daringdarius]

im gr.8 and it was kinda hard to understand because you do not organize your work on the board. (just a suggestion)

[JOSEANDJP32]

Im In 9th Grade And I Needed This To Pass My Class.

Thanks Man.

[110bloodlures]

thx... been watching and learning to ur video

Quite useful and much better explanation...

[joella32155]

Should I use the same step s to find the surface area of cylindrical grain silo with hemispherical top?

[BabelMath]

For the cylindrical grain silo with hemispherical top you would use add the lateral area of a cylinder (the rectangular part in my video) to the surface area of a hemisphere (which would be half the s.a. of a sphere). What I'm not sure of is if you should include one circle for the base, that would depend on the given information in the problem you are solving. If the base of the silo is just going to be dirt, and you want to know how much material is needed to build the silo, then no.

[myworldhasmusic]

@BabelMath i know this video is like 2 years ago, but i have a question, on 3:28, how did u get 25? sorry im only 12 lol

[legocloneking]

@myworldhasmusic he did the radius of the cylinder(5) and squared it because the formula pi r 2

[myworldhasmusic]

@legocloneking ohh! wow thanks! xDD

[Jesant045]
