Intro to Solids of Revolution (3 of 3: Other axes, volume of a sphere)

[MaeveFirstborn]

I just found this channel and I gotta say, this is some of the most entertaining math I've seen in a long time.

[pikachu]

SIR PLEASE DONT STOP MAKING VIDEOS. THESE ARE REALLY HELPFUL

[christir]

WOW! Such a succint explanation for the volume of a sphere! Blew my mind. Love it!

[jimmytan]

4:50 the upper boundary is supposed to be 9 not 2, for anyone confused

[MuhdiskandarDavlinfelix]

How I love math. Watching your videos at 5am. If my math classes was made simple when I was studying in high school.

[nayankishnani]

Why doesn't this have like a million views??

[gouravbanik]

Inspiring as always. Keep up the good work sir!!

[richardgarrison]

I would give this video a million likes if I could. I am having to code this and for the life of me could not understand it, but now I do. thank you so much.

[zefanyapardede]

okay, WOW i wish you were my math teacher. time to transfer schools...

[redsisco_]

if i had to describe the latter half of this video in 3 words it would be "cathartic sphere mindblowing"

[cheezkeyk]

The limits in terms of y should be 9 and 0. This is still amazing🥰🥰

[MartyThun]

How's your brain doing? 😅 Love it mr. Woo.

[bhavyajain]

ay^2=x^3 ko x=0 to x= 4a rotated about y axis then value of surface area ...
Sir please make video on thi

[noamroyale]

why are we not infegrating pie? or is pie integrated is pie itself?(this is a stupid question so please don't laugh at me) ( 8:37 ), I think that the integration of pie needs to be xπ because pie is just a number. (please answer this question 🥺)

[binzsta]

Isn't it suppose to be y^3, not y^2?

[skylar]

Isn't it supposed to be the square root of y??? x^2=y...

[jewel]

I didnt understand the step when he integrated r^2 = r^2 x

[mktz]

The bounds for you fist solid of revolution problem is 0-9 not 0-2.

[tgoh]

Why is the volume of the sphere the integral of pi y^2 dx? For the parabola y = x^2, but here y = sqrt(r^2 - x^2)?
