> A friend of mine tries to bake a spherical pie for pi day (March 14) each year, with varying approaches (and levels of success).

Could also do it on pi approximation day (July 22), then one doesn't have to be so exact about it.

Now I'm considering making a Matt Parker pie: a spherical pie made from a normal pie + calling it close enough in 2 out of 3 dimensions.

So a "Parker square" of pies then?

I didn't get it, so I looked it up.

22/7 ~= 3.14

355 / 113

( = 3.1415929204 )

is one approximation I have read about, attributed by some, to ancient or medieval Indian or Chinese mathematicians.

Actually closer to π and matches the more sensible date format.

(Yes this is worth fighting over!)
