solomonzelman · Answer

roughly speaking, there are 12 circles (piled up on top of each other).

So you need to find the area of one of the circles (all circles are the same, obviously), and then multiply the area of one of the circles times 12.

solomonzelman · Answer

what is the area of the circle?
(Use   ${\rm A}=\pi {\rm r}^2$  )

solomonzelman · Answer

or, same way you can just use the formula without conceptualizing it.

$\large\color{black}{ \displaystyle {\rm A}_{\rm~cylinder}={\rm height} \times \pi \times ({\rm radius})^2 }$
