which product, according to fda labeling, is raw, unprocessed, contains no preservatives, and has never been frozen or heated?

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
