Finding the Surface Area of a Cone.
See all Surface Area lessons: vividmath.com/...
Steps:
1. Find the radius of the cone. Simply divide the diameter by 2 (recall that the radius is equal to half the diameter).
2. Substitute the known values into the Surface Area of a Cone formula: (πr^2 + πrl)

In this video we use _π = 3.141592654_
There are different variations of *π* you may use:
Using _π = 3.14_ the answer is: *7706.816*
Why do you put the decimal so high???
Yep I solved it 7706.816
Bless this mans soul
It’s easy to say thanks but this genuinely helped me. 3 minutes of this video and i learnt more than an entire hour in my maths classroom. Thankyou
Thank you for saving my ass from the final.
its sad how all of the math teachers cant explain, sometimes i even think that they arent even math teachers. this video helped alot, even though the accent is a little bit hard to understand for me. thanks!
can you come to my school and teach
MonadoMudkipz lol
OMG THANKS SO MUCH I NEEDED THIS YOU SAVED MY LIFE MY MATH TEACHER DOESNT DO CRAAAP
Yep my teacher too.
same
he is my math teacher
5 years late but nice mordo profile pic
Thanks teacher
best math vid ever
This is such a simple topic, i got a 100 on measurement, though now it's come up again and i've forgotten alot of it D: thanks
I really hate to be Mr. Picky Pants but the way you write decimals could be confusing to some folks. The position of your decimal point is too high, as a result it could be mistaken for one of the alternate multiplication symbols.

true...
true Mr. Picky Pants
Your like that irritating chick no one likes at school
@@MuhammadKhan-ow5qf You're*
She’s the brony that always is right
Wow thanks the videos are really helping.
To be honest I so exciting with the you teach and it's help me a lot thank you, so let's move on with the area of the frustum.
thanks for helping me.. i got an graded assignment to teach my class how to do the cone and sphere i know how to do but you gave me a better understanding of it thank you. continue doing what your doing your great
Very helpful, thank you!
Thank you.
thank u very helpful
Thanks, this helped me a lot.
NICE
You sir are a lifesaver.
Happy to know the video helped you
tbh the formula for finding out the surface area is quite confusing. and, isn't it volume for the entire thing. I thought surface area was the area of the base??
This really helps smarty
Thanks it's very helpful. You did nice job thanks again.
UA-cam=Knowledge
☆Thank you sir🤝
i love u man saved me so much time i was trying to figure this out for 3 hrs but then u came
Lmao
thanks for helping
this equation made it a lot easier for me to solve.
good teacher
I really like the way you explain it.
youre amazing
u teach so well i don't understand y u don't give us access to more of your videos....esp. on algebra....
Sir, we know to drag nd drop the values from figure in given expression. tell us the maths behind how to obtain the expressions for surface area.
Thanks you so much helped me a lot. :)
thank you sir for giving me the formula....I'll use it for the PMR tomorrow...
You should do a video on how to solve for the absolute, and relative uncertainties for a cone.
wow i understood the concept from kenya👍
Nice I love it and understand it very well
Thank you for this. I'm in 7th grade but I'm just starting cones. It really helped
I'm 20 and just learning this for the first time! :) You'll master it
Im 10 and learning this 🙈
you're very helpful
Thanks for the help!
this was very helpful. thanks😁👌👍
Thank you
did my homework, thanks
pie x 26 x 68.4 equals 5587.0? I keep equaling to 5584.2 rounded to 5584 just ????
John Smith You are AWSOME TEACH ME HOW TO DO MATH

very clear! love ya
I love this but I had a thought: can you calculate the area of your nose?
Is this the guy in flash, the guy in a wheel chair lol
I watch that show! (:
Dr. Wells HAHAHHA LOL
Or you could call him Eobard Thawne
Can you post a video on locus
Go to mathsisfun.com
you may find some useful information on locus.
I found this to be very helpful and this saved my ass for my class tomorrow. If the guy instructing could be less of a hottie that would be great.
He should get to wear whatever he wants and look however he wants!
I want you to calculate the area of frustum
Thank simple and easy
Great help
THATS IS NOT CORRECT. A 5587,,ITS 5584 FRIEND..CHECK MAYBE I DID MISTAKE
I like you polo and thanks now I know what to do !
omg thanks alot
thank you!
he sneeze we all dead
thank you that helped
Glad it helped
So helpful
Having a brain fart in geometry thanks for this
Who taught this man to write a decimal?
yeah no kidding!
The Formula for TOTAL SURFACE AREA is different from SURFACE AREA of Cone ? what the formula for both? Please reply.thanks
How do you find the surface area without the base?
Umm I have a question why is the answer of pi x 26 sq. 2123.7 when the answer is 2122.64 so the answer should be 2122.6? I’m just wondering
its rounded to the nearest tenth
oh i get it i actually multiply it to 3.14 so i got different answer too
You need to consider placing decimal point at the base and after the numbers... it looks like you're portraying multiplication.
I need you to calculate the surface area of frustum and it volume too in the next video please.
thanxxx
you're welcome
thanks
Jesus loves you so much that he died for so please repent and spread the gospel
can you make a video on complete the square ? Its a confusing method :(
When I did it on the calculator, I didn't get those answers, but I got something close to it.
its rounded
ITS ROUNDED
Exams.......
Josh Friesen so
I have a test next period
Exam less than 6 hours
Help Me to 10k Subscribers for No Reason same here bro.
Can you explain why?
my teacher is called MR.doritos
Pato Yair
Mines called mr.dick haha
mine is called Mr. Lays
Mines Mr. WishIHadARealLifeInsteadOfThisMiserableWorkICallAJob...FreakingKids
mine is mr conery
Wow I understand it. Im no more feeling confuse.
Excellent
this formula does not work, I just put it into my math lab because their formula is confusing and the answer came out wrong theres square roots involved and this is not using them
It works, you are just over thinking it.
stop scribbling on the board on your final answer
The Polo shirt ;)
68.4 good example number
So like I went to this academy and I’m only 12 and they gave us this kind of math and it’s reallyyyy confusing
What is the average of pie
I dont how to multiply
3.141592654
man my teacher sucks at sait she doesnt compare to this teacher can you teach her please lol thank you this helps me so much excellent i love watgching your math videos
Why does he look like Aria's dad, Montgomery from PLL? Lmao
Finding out the surface are of my joint
Why the hell is your "point" in the air ? it's supposed to be on the bottom
Why do you use an X for multiplication. Wouldn't it be nicer to use an * instead?
+Martin Nolin
i use a dot *dont be picky*
omg i am so confused, at school i was given the formula including the angle of the curved area and i dint understand it and i tried to use this formula but the answer came out wrong somebody heeeeelp
I missed a day of school, and that one day we had 35 problems, when we normally have 20 ish, counting today I have about 70 problems, and it is all on stuff that we learned at the beginning of the year, so I don't remember, and I've been stuck here for 2 hours getting, just my math done, and I still have science and language arts homework....smh
Season 7??
Wut?
In fortnite I only have too wins my player tag is TheOfficialGamer
How do you work out the 68.4 i was only given the height
Pythagorean theorem
'S' stands for slant height..
what if the cone doesn't have a radius
King Kee Then it’s unsolvable
its does, if the diamter is given, then just measure urself.
and u sir sound like a ZED the master of shadows
Atleast proof how did this formula came? Everyone knows how to memorize and apply the formula.
I do not understand his rounding. Either that or my calculator is no good.
And here we have another dead education channel.

The formula tells u everythin
