Correlation of two variables correlation coefficient between rows

I have two variables the radius and the mean value of the values inside this radius. The radius gets bigger in a linear way at a fixed step size. The Rows represent the observations e.g.:
radii value
11 5*10^-4
21 5*10^-4
.. ..
when i use corr / corr2 /coeff
>> corr(radius_bla_rot,field_1_mean_rot_90)
ans =
0.0930
>> corr2(radius_bla_rot,field_1_mean_rot_90)
ans =
0.0930
>> corrcoef(radius_bla_rot,field_1_mean_rot_90)
ans =
1.0000 0.0930
0.0930 1.0000
I just get one value (0.0930) which tells me that my data has a weak correlation. And now I want to see if there are some radii which correlate and then when the radii get too big there is no more correlation. I have attached the data I am working with right now.
