It's also horribly inaccurate.  I carried over to the Apple II the same
practice I picked up from the manuals for my TI-99/4A:

PI=4*ATN(1)

It takes slightly longer to calculate, but you only calculate it once.

Integer BASIC != Applesoft.  The former was limited to 16-bit integer math,
while the latter does single-precision floating point.  Applesoft also
allows character arrays; Integer BASIC doesn't.  OTOH, Integer BASIC was
supposed to be somewhat faster at some things...I guess that says something
about Steve Wozniak's coding skillz vs. Bill Gates' coding skillz. :-)
