    think about doing the surface area of the outside, plus the surface area of the top and bottom

    so, the area of a circle is \[2\pi r^2\]

    then the circumference of a circle is \[2\pi r\] and you will multiply that by the height to get the surface area of the rest of the cylinder.

    no problemo. and remember that you have to add the areas. area of ends + area of rest of cylinder.
