r = theta (Cinnamon Roll)

A delicious Calc 3 instructional aid. Made in Mathematica with the following code:

CinnamonRoll =
RevolutionPlot3D[{r = theta/Pi, z = Pi*t}, {t, 0, 2}, {theta, 0,
6 Pi}, BoxRatios -> Automatic, BoundaryStyle -> Black,
PlotStyle -> Thickness[.2]]

This could also be called a Fruit Roll-Up without much protest.
