Is it? If you call

objectoGrafico.getRenderType()

what value do you get? The values are stored in OMGraphicConstants.

You can't reset the rendertype and expect to get the internal values
translated. The render type just indicates which fields contain valid
data. By changing the render type, you do not populate those fields.

My guess is that the render type is RENDERTYPE_LATLON - and you have to
call getLatLonArray() to get the values, which are in radians.
