In general, what would be a function for finding surface area of a cylinder, top and bottom included...?

f(x)= something + 2(pie)(r-squared) I believe...don't know how to get the surface area of the round part of the cylinder, only top and bottom.

the total surface area
=lateral surface area +the top surface area+the base area
=>2pi*r*h+pi*r^2+pi*r^2
=2pirh+2pir^2
=2pir(h+r)sq.units

Area of a cylinder = 2pi*r(h+r)

multiply by height the surface area of the circle, like you have up there, pi r^2
