Question

Find the curved roller surface area and total area and total surface area of cylinder with diameter them and height an.​

Answer 1

Answer:

hi

Step-by-step explanation:

let's take

diameter,them=x

and height, an=y

1)curved surface area=

$2\pi rh$

2)total surface area =

$2\pi r(h + r)$

Now substitute,

1) 2π*x/2*yπ

=2πxy/2

2)2π/2(h+r/2)

=π*2h+r/2
