Why Use 3.14 for Pi in T = 2(pi) / w?

[Darth Frodo]

When I'm using formulas such as T = 2(pi) / w I thought Pi should be in Radians as w is in rad/sec yet when I look at an example it uses 3.14. Why is it 3.14 instead of 180?

$\pi$ radians is equivalent to 180 degrees.

Thanks. A major brain fart on my part.
