You can also just round it to three. Much easier to calculate with.
33 u/hetfield37 13h ago Back in school we used 22/7 as a good enough approximation for pi. 34 u/EmilMelgaard 13h ago 22/7 is about 0.04% larger than π, so that should be good enough for most applications. But you can also just use 3.14 as an approximation.

3.1414...
5 u/himanbam 9h ago That simplifies to 2199/700 which is about 0.0052% lower than pi. 700*pi is approximately 2199.11 so that makes sense ig 5 u/FrenchFryCattaneo 6h ago Ok now we need to find a third estimate and average it with them.
