I am not sure I have interpreted your question correctly...

Explanation:

I think of (uniform) velocity, say, in a typical periodic rotational motion where you have:
$v = ω r$ $v=omegar$
where velocity (linear) $v$ $v$ is related to the "circular" corresponding velocity called angular frequency, $ω$ $omega$ .
Angular frequency is a kind of circular velocity because it tells us how many radians are described in a period of time so to complete a circle it will take a time called Period (the time to complete an entire circle) $T$ $T$ :
$ω = \frac{2 π}{T}$ $omega=(2pi)/T$
Period is related to frequency $f$ $f$ as: $T = \frac{1}{f}$ $T=1/f$ :
and so:
$ω = 2 π f$ $omega=2pif$
Collecting all our information we get:
$v = ω r$ $v=omegar$

$v = 2 π f \cdot r$ $v=2pif*r$
so that we can evaluate frequency: $f = \frac{v}{2 π r}$ $f=v/(2pir)$
