Ninth Circle of Dante Alighieri's Inferno

American popular culture often characterizes Hell as a place of heat and fire and burning, but as we go through Dante's Hell-scape, fire does not seem to play that big of a part. Focus on one circle of Hell, and discuss its punishments; how do the punishments there relate to the crimes committed by the inmates? Support your response with specific passages from the text.
I need this to be an original answer, it will be check by turnitin in my class.
Thank you in advance.
