What is the Volume of a Cone? - [8-8-9] 

You're the best math youtube teacher hands down

Mr. Jason is sent from another planet. He is so unique, unbelievably talented, completely out of this world. Thank you so much. You are doing an amazing thing for the humanity and I do really mean it.

What a good teacher 🙊you make things easy thank you so much sir🤝

Excellent instruction. Thank you!

Thanks Sir 🤝🤝💯

Excellent instruction once again, thank you.

Thank you Sir 🙏

You are great.

you are the beast teacher thank you for everting.

Thank you ❤❤

You are a very good teacher. After that, we have many lessons and we are with you in spreading the word.

And I love your explanation they are all on fire 🔥🔥😂😂❤❤

THANK YOU... SIR...!!! It was easy...!!!

Tanks teacher!!!

I like the way explain 1/3 is great to learner easy the standing. I am Vietnamese to learn math by English, because i can not find good teacher like you in RU-vid. Thank you alots. But why r2?

A very practical lesson would be to find the volume of cones that have some amount of area on the small end. IE a cone with 4cm base and 1cm tip.

Nice 👍

What if the apex isn't central above the circular base? Is it the same formula, like an obtuse angled triangle

I wonder if tippy top could be relabeled as Apex.

What to do if it has a remainder when dividing ?

save me!!!! thank you!!!!!

v=1/3(3.14)(4 squared)(8)

v=1/3(3.14)(3 squared)(6)

Isn't it 16.746 cm cubed? Why is the answer 17.746, you started with 16.746. What did i miss? Thanks!

Can u next do the area of a cone

v=17.1 remainder 6 round off to the nearest hundredths

16.746 or 17.746??? At 6:20

v=130.31 remainder 1 cubic meters

v=1/3(3.14)(128)

v=7.32 remainder 2

How did the one third come about

v=1/3(3.14)(16)(8)

v=130.31 remainder 1

v=1/3(3.14)(54)

v=7.32 cm cube 3

The formula only works with the vertical height of the cone. If given the slope height of the cone, you have to work out the vertical height by solving the trigonometry of the triangle to find the vertical height.

376.8 mm cube 3=1/3.68.04/1 h

376.8 mm cube 3/22.68=h

volume=376.8 mm cube 3

376.8 mm cube 3=1/3(68.04)h

376.8 mm cube 3=1/3(3.14)(36)h

v=56.52 mm cube 3

v=1/3(3.14)(9)(6)

v=1/3(3.14)(6 squared) h

v=130.31 remainder m cube 3

v=1/3(169.56)

v=1/3.169.56/1

In philippines grade 6 students learn how to calculate volume

376.8 mm cube 3 =68.04/3 h

v=169.56/3

v=7.32 cubic centimeters

v=1/3(392.94)

v=1/3.392.94/1

Bro looks like Phil swift😂

v=56.52 cubic millimeters

Fun fact: there are no visual or geometric proofs that explain WHY the volume of a cone is 1/3 the volume of a cylinder without bringing in calculus or by saying “because I said it was 1/3”

v=1/3(3.14)(36)h

v=56.52

376.8 mm cube 3=22.68 h

v=1/3 pi r squared h

v=1/3 pi r squared h

v=1/3pi r squared h

h=17 m

find the x height

If the formula is true,3 cone icecream should fill the cylinder of same radius.

🌟🌟🌟🌟🌟🌷

i dont understand why it has to be upside down icecream cone

hahahaha

First proven by the great Archimedes :)
