Question

so, 2 times pi.

what?

Can you better explain. I'm sorry, I just need better explanation.

Aphmau · Answer

For a cylinder, there is 2 kinds of formulas the lateral and the total. the lateral surface area is just the sides the formula for that is 2(pi)radius(height). the formula for the total surface area is 2(pi)radius(height) + 2(pi)radius squared.

sure

it would initially be $ 2πrh+2πrh $
therefore, the total area of a cylinder would be $ 2πr(r+h) $

lapsus

i mean \  2πrh+2πrh^2  \) lol!
