How to plot this implicit function？

I have the following equation:

100 =(9*(Delta/10)^(1/2))/125 + (pi - atan((18*f*pi*(Delta/10)^(1/2))/125))/(2*f*pi)

I want to plot f vs. Delta

How can i plot this function?

(My Matlab version is R2015)

Thank you.

It doesn't appear to be a very interesting function.

fun=@(Delta,f) (9*(Delta/10)^(1/2))/125 + (pi - atan((18*f*pi*(Delta/10)^(1/2))/125))/(2*f*pi)-100;

fimplicit(fun)

Warning: Function behaves unexpectedly on array inputs. To improve performance, properly vectorize your function to return an output with the same size and shape as the input arguments.
