#PiApproximationDay
22/7
#PiApproximationDay
Almost missed #PiApproximationDay.
Today is July 22nd, which some people might write as "22/7".
22/7 = 3.1̅4̅2̅8̅5̅7̅, which is reasonably good as an approximation of π with an error of 0.04 %.
Other neat approximations include:
1337% of π equals 42 (error ~ 74 ppm)
355/113 (error below 100 ppb)
and my favourite:
π⁴ + π⁵ = e⁶ (completely useless, but nails π to 9.2 ppb!)
Do you know any other approximations for π?
Meanwhile, take a look at my wife's car.
Happy Pi Approximation Day! Remember, “Failure is just success rounded down.”
It’s #PiApproximationDay! So here’s a video that’s approximately Pi(e):

Happy Pi Approximation Day!
(Sadly, this day is always in a holiday, so I can't teach about π today)
Pie are square. Pie are mot square. Pie are round. Cornbread are square! #PiDay #PiApproximationDay
Happy Pi day to those who celebrate! #PiDay #PiApproximationDay
He understands why Pi is what it is, but a perverse part of him still wants to round it up to 3.
On this glorious
be sure to remind everyone you see how many digits of Pi you memorized!
@steve_gibe don’t worry, us brits have #PiApproximationDay to look forward to!
And to conclude π-approximation day, I am going hapπly off-πste and πgging-out on a πece of πzza #PiApproximationDay #πApproximationDay

An irrational number named pi
Said 'I feel a little bit shy
When the folk make a scene
About March, day fourteen.
I prefer twenty-second July.'
Happy Pi Approximation Day! Remember, failure is just success rounded down.
To celebrate π-approximation day this year, I'm starting with an apricot frangipane tart. #πApproximationDay #PiApproximationDay
Mais au fait, j'ai failli oublier !
Aujourd'hui, 22 juillet ! C'est la Journée de l'Approximation de π (Pi)
Bonne fête à tous ceux qui aiment les #Mathématiques !
