Answer 1

well in this question they are finding the surface area of a cylinder

Answer 2

The formula for that is 2πrh + 2πr^2

Answer 3

ya @kelgendi1 is right so u must use \[2 \pi r h+ 2 \pi r^2\]

Answer 4

so (2π*20/2*10)(2π*20/2^2)

Answer 5

@9ix9ix can u understand

Answer 6

do you understand how i plugged the numbers in the formula
