Question

What is the surface area of the cylinder?
Diameter of the circle=12
Height of cylinder=15
I keep getting 791 and its not an option.

Answer 1

WAIT, derp I am stupid, friggin pie is part of the answer, let me just go cry in a corner

Answer 2

surface area = \(2\pi r^2 h + 2\pi r h\)
since diameter = 12 then that means radius is 6

\[SA = 2 \pi (6)^2 (15) + 2 \pi (6)(15)\]
\[SA = 2 \pi (36)(15) + 2 \pi (90)\]
is this what you did?

Answer 3

oh lol

Answer 4

Yeah, I was doing it the more difficult way I guess, thanks for helping though!

Answer 5

<tips hat>

Answer 6

Wait, @lgbasallote I think the formula is \(2πr^{2} + 2πrh\)

Answer 7

oops lol yeah delete 15 there *facepalm*
