The lateral surface area of a cylinder is the area of a rectangle that has as dimensions the circumference of the base and the height of the cylinder.
$LA = 2 \pi r h = \pi dh $

kay. so what do i do now? @mathstudent55

mathstudent55 · Answer

$LA = \pi d h = \pi \times 12 ~cm \times ~18 cm $
Just multiply it out.

anonymous · Answer

this is wat i got( 678.24) i dont think i did it right

mathstudent55 · Answer

Notice the answers have $\pi$ in them. Just multiply 12 and 18 and leave $\pi$ in the answer.
