Best ResponseYou've already chosen the best response.0By my calculation, the length of the minor axis is 185.9931182. I got this number by using the formula for calculating the focal length of an ellipse, which is \[a ^{2}b ^{2}=c ^{2}\]. Rearranging this formula to make use of my known data (that A=186 and C=1.6 [remember, the focal length will be HALF of the distance between the foci]) I get \[186^{2}b ^{2}=1.6^{2}\]. Solving for b, I get \[\sqrt{186^{2}1.6^{2}}\], which is approximately 185.9931182.
