Toroidal Carbohydrate and Fat Containment Device

If you’d like to work out the approximate surface area of this Torus, it’s simply a matter of finding out the inner radius (r) and the outer radius (R) which will give you


Of course for volume you’d save yourself the trouble and immerse it in a measuring jug of coffee.

    Torus? It barely touched us.
    BTW does your camera have a cuisine setting?

    Oh wow, no. Benri da ne!

    Bet it slices a mountain of coleslaw too.

    Hi Anthony,

    Fascinating facts. What kind of torus do you think this is? Looks more like a horn torus to me. What was the measured surface area of these beauties?

    By the way, did you make them yourself? The pictures look great!

    I didn’t know Dr. Stephen Hawking was guest blogging this week. Whassup?

    Icing had in fact transformed it into a horn torus so I unblocked it with a chopstick this returning it to its natural state. Sadly it was eaten before I could get the micrometer out but lets say

    No, no donut maker me, but it’s the same donut with different lighting on a translucent counter.

    I’m dedicating this post to you.

    I like this post for the following reasons:

    1. I’m a Taurus. Torus, Taurus. Close enough.
    2. It contains the word “coffee”.
    3. It’s got maths.
    4. Inner and outer radii make me hot.

    Is it just me or is that a surprising amount of surface area for a donut to have? I would have thought around fifteen… but jeez, it’s quite a lot more. Are you sure you did the maths right? Because that’s a lot of donut-area. Just think about it… 37 square cm. Wow. This donut-science is really doing my head in.

    Temporally mapped inner and outer radii make me pretty hot too.

    That is the beauty of the torus over a bun shape.
