the algebra part seems too basic, too pedantic (like you don't cancel out 3's, you do (3/1)(4/3) = (3*4)/(1*3) = 12/3 when you only have to do 3 * 4/3 = 4) but I would rather have focused on the first part of it. but the first part is good anyway, even for using fake calculus
@ravencaliber Incorrect, the volume of a sphere is (4/3)Pi*r^3, the equation in your post is the surface area of a sphere. Also to progress from simplicity we must approach the complex. Understanding these derivations are important for discovering new things.

I just find it ridiculous that my teacher was SO lazy he wouldnt teach us this so he had us watch a video of him talking.

why couldnt we just have this taught to us in person?????

@spickole derivation of formulas like this isnt usually taught because it takes to long and sometimes isnt udnerstood and its just easy to say
remember that the volume of a sphere is 4*pi*r^2
and instead of remembering the derivation a simple line like that is a lot easier.
