I need to find which latitude has the smallest radius.

40°30'13" or 30°40'13"

-None-

I converted from DMS to degree and got:

40°30'13" ≈ 40.72° and 30°40'13" ≈ 30.88°

Since the Earth is not a perfect sphere, I said that 40°30'13" has the smallest radius because it is farthest to the equater, meaning the farther you are to the equater, the smaller the radius.

I don't know if I did this right because I think it is means that each latitude has it's own circle, but I don't know how to get circles from latitudes.

Am I correct in my assumption that 40°30'13" is smaller because it is farther from the the equater?

*Knowing that at 0° the distance to the equater is greatest because of the elliptical form*
