Oops! I left out one thing you take the final calculated value and multiply
it by two because in making a rolled capacitor you put the outer plate
opposite itself thus doubling the capacitance. Sorry about that! So actually
if one thinks about it there is a special equation for rolled capacitors,
but it is derived from the basic plate capacitor equation.
