Question 6206
if you think about slicing a cylinder lengthwise and unpeeling it, it would look like a rectangle, right?  (roll up a piece of 8.5x11 paper and it makes a cylinder)
so the formula for the surface area will be length * width. the trick here is to remember that the length will be the height of the cylinder, and the width will be the circumference of the cylinder:
circumference = 2pi*radius
so the area = 2pi*radius*height
the volume is the area of opening to the cylinder * height
{{{pi*r^2*h}}}
so the volume + surface area = 
{{{pi*r^2*h+(2pi*r)}}}
