Please let me know if I did this correct for b... 100=C/(3,963)^2 100=C/15,705,369 100*C=(C/15,705,369)*C 100C=15,705,369 100C/100=15,705,369/100 C=157,053.69

Ok, I went back and tried again. The equation I found when solving for r is r=sqrt(C/w) Is this correct? Then in b I would plug in the 100 for w, and the 3,963 for r to find the constant, C, correct?
