Question

I've been taught by my math teacher that pi = 22/7. Is that true?

Answer 1

Yes, that's correct. However, many of us prefer to use the decimal equivalent: 3.14

Answer 2

But 22/7 = 3.142... and pi = 3.141... It appears that they're not equal.

Answer 3

They are not exactly equal. But most teachers recommend you use 3.14. If you want to use a more accurate number, you could use:

pi = 3.14159265
