Surface Area Of A Cone - Slant Height Not Given 

Thank you for taking the time to post this video! It really helped a lot! Thanks again!! You have my gratitude for making this video

It's been many years since I had to do this in college. Now that I am homeschooling I needed a refresher, this was a big help.

You saved my life, thanks for making this video, keep doing these please🙏

2021 and still doing miracles

This really helped ...Thank you so much

Why the square root and hole root cancelled

thank you so freakin much!

love you man. that helped

Thank u lord Jesus!!!!!!

That helped me understand slant height I never thought it would be this EZ thz

I dont care if this video is 8 years old, it helped me through highschool

Hopefully someone would answer. Now How would you find the leg without the height given or find the height without the leg given? Please and thank you.

Length of arc of a circle with radius 5cm is 10cm find the area of corresponding sector........

Alleh guy. GENUIS. Thx

can I ask you something , in what ages europeans learn this at secondary school ?

thanks for using the exact numbers that my problem was using🥵

Omg, this helped me so much! But question, what if i was given a question like calculate the dimension indicated by the variable to the nearest tenth of a unit? And i was only given sa=7012 mm^2 and base was 48mm and no slant height or height of the cone? Do i still use the a^2 +b^2 = c^2 formula? -___- i would be in debt if you helped me.

Omg thank you so much im sure this will help me in school

Thanx man

thank you I forgot how to do it thanks again.

I just saw someone talk about how he did this in college I’m doing this in 7th grade

thanks mate

Can I ask? How did you get 17 from the square root?

my teacher did something like this but he did not square root the number when doing Pythagoras.. he put it in the equation when doing the surface area... is that another way of doing?

dude your really good and everything but you loose me for a while when you say all the names and stuff just say a+b=c it would be soooo much easier

I’m watching this while doing a math test

i dont have the height or slant height

DID NOT HELP. but thanks for the effort
