But how can the lateral height of cone can be height of triangle because the height of triangle is always perpendicular

How to convert area in to length and width i.e it shows net & gross both

Sir the base b is curve so how can we take this as base?

[@kailashgoel4418]

Nice

[@swastikkandpal]

Thanks sir from lakshmi sir

[@mmmk987]

Sir you divided a circle in triangles but it doesn't have a straight base . It is curved so they are not triangles but they a sectors

[@krishnasaha361]

Sir can t make that small triangles needed for the bse to be straight ☺☺

[@kornanajayakrishna4321]

That is not a traingle..its samm small size sector..

How angle formed 90 degree in each triangle if 90 not formed then we can't use 1/2*b*h anybody help me

[@flatearthasmr9034]

Unfortunately Pi cannot be used for calculations for constructing a cone and a cylinder with the same definite r & h. Phew = 3 17157 shall replace Pi = 3.14159.

[@adiliraliyev5882]

Thx, good video, understand, however could've been better, with CGI or better practiced video; not the least, thx u.

[@Bodhaguru]

Glad it helped

[@sunilkumar6779]

Sir,
I need to know why height 'h' is taken as 'L' , as in area of traingle we take height as 'h' but why it doesn't matter for cone?

[@louiselin3928]

Since the "L" he meant here is the side length of the cone, not the height of the cone

[@Adiedits421]

I have a doubt
There i see height = radius
