#Wanna know about my incorrect reasoning

Okay, so imagine a circle or radius r
imagine uncurling the circle's circumference into a line
so the line will be of 2pi * r
Now since the radius at each point constant, multiply 2pir by r, so that it will conver area of circle by radius
result will be 2 * pi * r^2

I know this is not the correct proof
However, I wanna know what am I reasoning wrong.
This looks plausible to me.

what are you trying to provea acc

last cobalt
#

area of circle

like, see, I am having an inuititon about rotating a radius of r 360 degree, and the distance covered would be 2pir, with constant r

#

idk how to explain here sry

#

that should give me the area by accumulating all radiis

#

for example take a rectangular paper and try to twist into a circle see if it happens

yeah, I know it is not reversible
but I also wanna know what exactly did I do wrong when I multiplied 2pir and r

#

oh wait

#

OH

#

I got it

#

thx man
