Surface Area of a Half Cylinder - VividMath.com

[@VividMath]

In this video example we use _π = 3.141592654_
There are different variations of π you may use:
Using _π = 3.14_ your answer may be slightly different.

Please stop writing your decimals in the middle it looks like you’re multiplying when you aren’t 😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭

[@shilahriddell813]

It felt like we were in the same room, I was filling in my own measurements and I barely had to pause.
THANKS SO MUCH :)

[@johnmckayjr]

Excellent explanations, calculations, drawings, and use of the equations.

[@AA-xd9mj]

This guy deserves an award for simplicity 🔥🔥🔥🔥🔥

[@sanjaydajibhai4873]

An amazing video cuz I have a test coming up and I thought I was going to easily flunk it. BUT NOT ANYMORE THANKS TO THIS VIDEO!! thank you so much!

[@zahraraisa4626]

THANK YOU FOR MAKING THIS. This was just really simple and easy.This helped me alot.Thanks again.

[@endcode]

this helped so much thank god you made this video :)

[@justinkillsaquino]

Thank you so very much. For the past 2 days, I've had so much trouble solving a similar situation in my workbook, but thanks to you its all good now :)

[@yubbityyubba7749]

He's a legend isn't he

[@justinkillsaquino]

+Adam's apples he great. it was so helpful

[@yubbityyubba7749]

+Justin Kills Aquino I watched the video still confuses me lol seems to go against all cylinder rules and is much more complex than open or closed cylinder ones but he's still a legend

[@justinkillsaquino]

Adam's apples I perfectly understand it lol

[@yubbityyubba7749]

+Justin Kills Aquino I guess I'm a little bit retarted than

[@breannanewcombe3354]

Thank you so much I was so confused when I found this question in my homework, but you should really add the formulas for each surface such as lw (length x width) for rectangle other than that it was very helpful

[@user-xt7jq8qp9x]

Yea true that’s what I did in my working out lol

[@lightningthehedgehog112]

Ha fooled

[@thesimplechannel8891]

The easier way to do this question is: {this is the formula for a half cylinder}
A = 2[1/2*PI*R Squared] + 1/2 (2*PI*R)*L*B*L

[@danmark9255]

hey what is b

[@randomrom747]

@Guppa Ejee So cylinders breathe now?

@@danmark9255 base lol

[@user-xt7jq8qp9x]

Internet imaoo lol it’s base😂😂

[@trkennel]

isn't A = 2[1/2*PI*R Squared] + 1/2 (2*PI*R)*L + B*L
the right one? you forgot to put a plus between L and B

[@amandamarasco7530]

omgggg this helped so much thankyou, I had a question like this in my homework, thankyou for helping :)

[@sarthakmohapatra3738]

Excellent video sir. Thnx a lot

[@RLTC208]

[@lanak5085]

Very good explanations in all of the videos :)

[@RamiPan-g3p]

Thank you so much :)

[@ethanchong1384]

bro this is a great explanation thanks

[@VividMath]

You're welcome

[@taekwondoman2D]

very good video it helped a LOT!

[@FIRSTLAST-wi3yk]

thank you sooo much 👍

[@dunamis9313]

This video was very helpful. Thank you

[@David-fx3kv]

It very helpful. The explanation are good and word that came to show. It a good helping math.

[@ryanlenders9856]

very helpful !

[@srini752]

I have a question. Can you find the area of the whole cylinder and then halve it? Any suggestions welcome

[@loricarrel6889]

Test it out because I was thinking the same thing

[@rafeeali1203]

nope because you would be left with a unsolved base

[@lovepassion5913]

Thanks for that it's really helpful.

[@ppxhero1170]

Good Teaching!

[@user-xt7jq8qp9x]

The thing is with this is that when people look at the working out for the first time thier like 😳 but once u do the working out it’s easy as

[@bernadetteroberts]

Thanks!

[@nimzo7933]

What if it is half a drum that was painted both in&outside

[@nimzo7933]

Plz!!!! Reply to me 😑😔

[@shamalusmith2988]

Could i use the formulae for the surface area of a cylinder and then divide it by 2?

[@rileythorn4928]

No not Really because there’s the extra face at the bottom

[@sharonkiptoo7655]

Thank

[@benjamindenham1415]

You are amazing

[@user-xt7jq8qp9x]

2:32 well actually the way I do it I actually put 2 in the formula at first itself

[@dorcaswanyeki6061]

Thanks so much t

[@dorcaswanyeki6061]

Thanks so much ,the video really helped me

[@davidmpande3738]

Find volume now

[@musabmahammed6686]

The guy is looking at the side of room as the results are on their.Is there a video on how to find out the volume of a half cylinder.

[@bransonmcmahon]

To find the volume just find the area of the half circle then times by height

[@CryptoSeann]

i like how he stands 0:43 . this is call guys twerking xD

[@Zolbandoy]

Howd u get the 32?😩😭😭

[@mileseyre1636]

Alan 😂😂😂😂

[@LaxmanGite4435]

good morning

[@luqmanboy4590]

Were you sleeping

[@ashton1155]

good vid

[@mariamhaque3164]

Oh very good

[@aamirabdulsalam]

yeah

[@amigloss7627]

its πrh+πr^2+2rh

[@janavukicevic4896]

OMG I was ssooooooooooo confused by this video u didn't even explain I have a test tomorrow and I have no idea what to do. Thanks for nothing. Soz no hate plz this was just my opinion

[@thesimplechannel8891]

yea ikr, he cant explain shit.....

[@endcode]

or maybe you just skipped to the ending of the video

[@metronini]

your a piece of shit haters

[@mourii8643]

Know the formula first you dumb

[@kalokohang9130]

So much mistakes in solving but the solution is good

[@DogMann32]

Can you be my math teacher pls

[@krishnapoudel6596]

Rip

[@saritapunia3720]

its a very simple thing for an indian btw

[@CryptoSeann]

anyone find this guy is annyoing

[@alfredocadionjr.7519]

my answer is 6,483.48

[@alfredocadionjr.7519]

using this formula 2π r ( h + r )
