To four decimal places, 3.1416 is better -- to five, 3.14159 (the 5 gets rounded up due to the 9 following).
I don't understand why my answer has been rejected. I put: ττ, ττι
You typed the letter tau twice: τ τ
Instead, type the letter pi once: π
Or type the letter pi and the letter iota: πι
(ττ = Τ Τ is not the same as π = Π, just as rn = R N is not the same as m = M, even if they look similar when close together.)
Thank you for your help. I can't wait to try this out! Also, I'm very impressed with the quantity of languages you have tried. What is your native language?
My mother tongue is German and my father tongue is English :)
makes no sense. Says that the n, ni is correct, and i put just n. (Can't do pi symbol. It was multiple choice).
I put pee and it let me carry on .
US/CA keyboard, type: pi
Greek keyboard, type: t
(English to Greek)
Wait, this is different as duo doesn't usually use pi.
η how come i typed this and it shows that's it's correct?
They gave me π as a another correct answer. Shouldn't my answer be wrong?
Once again typo in my answer but it is just wrong. It should have been fault........
