Answer 2

Well, can you find the surface area of a cone?

Answer 3

There's like two different formulas
Something about regular and circular?

Answer 4

You can imagine cutting the cylinder down the side: So you know how to find the area of rectangles right? So if you cut off the surface and turn it into a rectangle like this, then you can see how the height and circumference of a circle are the area.

Then remember the bottom also has area of a circle.

Then you add up all 3 of these together. I'm not sure off the top of my head about the cone section but you can probably find it on the internet.

Answer 5

So I do 6 time 2? For the cylinder?
