Question

Find the exact value:
(pi)/12

Answer 1

pi=180

Answer 2

Thus Pi/12 = 15

Answer 3

that's if you're thinking of pi as radians, which you probably are, right? otherwise you can't find an exact value.

Answer 4

no, the question wants the EXACT value! start getting your CRAY supercomputers out, we got billions of digits to calculate!

Answer 5

0.26179938779914943653855361527329

Answer 6

Edit: Should come out as a fraction.

Answer 7

use pi/3-pi/4

Answer 8

use pi=3.14
3.14/12=.2616

Answer 9

pi is not equal to 3.14.

Answer 10

using in trignometry pi =3.14 or 22/7

Answer 11

That's an approximation. It would be like saying that pi = 3.

Answer 12

no

Answer 13

Sorry to say it, but you can never write down the exact value of pi in decimal notation, or as a fraction. pi is proven to be irrational, which means that pi cannot possibly be equal to the value 22/7. It's just an approximation. It's fine to say "pi is approximately 22/7". But it's definitely wrong to say "pi is equal to 22/7".

Answer 14

At any rate, 22/7 has an infinite number of digits. Rounding off, 22/7 = 3.142857142857142857142857... But you also say that pi = 3.14? That should throw you some hints that you should rethink the idea that pi is equal to 3.14 and to 22/7, since they are different numbers to begin with...

Answer 15

I believe the formula needed is a sum and difference formula but I'm not sure.
