Hi there. Why did you remove your old videos? They were so helpful I alway referred back to it.

[malikahcanfield]

when you calculated TSA of the cylinder i got 119.396, how did you get 232.51cm

Ma'am do you know your a God sent angel ❤❤❤ Thank you a bunch Ma'am ❤❤❤

[_thumtha]

Ma'am you are so brilliant your videos/lessons are thee best, much love

[dimphomotaung]

how did you get the answer for the cylinder in the beginning of the videos
my answer was 119, 396

[Mr.Peanutbutter]

The TSA for a cylinder is 2(π x r²) + 2(l x b) I did it just as 2 x π x r² + l x b and we got different answers

Please insert a calculator for your videos because your answers match up with mine I want to see how exactly you work with your calculator

[EnosIsheloke]

Hello mam, i don't understand. Why when you calculated the base of the box, you didn't times 2 at the end coz the bottom also has two sides. Back and front, left and right?

[singitafaith]

Any one else struggle to get the answer for TSA for cylinder, if I type in the last equation before the answer I get a different answer & I’m typing it exactly the same .
