Question

Can anyone tell me the formula for the surface are of a cylinder. I can do the math, I just need the steps.

Answer 1

S = 2*pi*r(h+r)

Answer 2

s = area, r = radius, h = height

Answer 3

you use the radius twice?

Answer 4

yep.

Answer 5

okay. Thanks!

Answer 6

How do you get this formula:
The base area = pi*r²
The lateral area = 2*pi*r*h

The surface area = 2*base area + lateral area, right?
So,
2(pir²) + 2pirh = 2pir(h+r)
