I draw a Geometry (Circle) and try to get its diameter by Geometry.Extent.Height. However, if i manually try to see the distance in a arcgis web map, it differs significantly. Like, 1800m from Geometry.Extent.Height is actually 1200m in web map.
I tried to do the same in the some part of the equator of world map and it actually matches. I don't know why this is happening. Is this scaling issue? Any advises on how to make it give the same distance in both?
