Answer 1

help someone

Answer 2

2 pi r^ 2 + 2 pi r h

Answer 3

so is that the formula?

Answer 4

wait
is it 2pi r^2+2 pi r H/4

Answer 5

Yes.

Answer 6

ok thx can u explain to me caus i want to understand it

Answer 7

nvm i have a new question

Answer 8

so i will close this one can u help me with other one too

Answer 9

Wait do you understand it ?

Answer 10

yeah

Answer 11

h is the height of the cylinder, r is the radius of the top
Surface Area = Areas of top and bottom +Area of the side
Surface Area = 2(Area of top) + (perimeter of top)* height
Surface Area = 2(pi r 2) + (2 pi r)* h

Answer 12

yeah i got it

Answer 13

i have a new question you can check that out

Answer 14

Okay.
