If a math teacher asked you to determine whether a point was (strictly) within
a circle, he'd write
|p - c| < r
Somewhere else he'd define
____________________________
|p - c| = \/ (p.x - c.x)^2 + (p.y - c.y)^2
and somewhere else he'd define
foo.x extracts the x component from a Cartesian point foo
You wrote exactly the same though with bad choices for the names and with a bad
ordering of material.
What part are you unhappy about?
