Hello, I have to write rules which will transform the cartesian coordinates (x,y,z) to those in cylindrical polars (r, theta, zd)

x = rcostheta
y = rsintheta
z = zd

I was thinking of something like:

x[r_,t_,d_]:= r Cos[t]
y[r_,t_,d_]:= r Sin[t]
z[r_,t_,d_]:= z d

I then have to test this on the vector {x,y,z}. I have to calculate the length of a vector {x,y,z} by writing a rule to do so and finally calculate the length of the vector in cylindrical polars using another rule.

Can anyone give me any hints? Is what I've done so far correct?

Thank you in advance.
