October 17, 2012 at 6:09 pmLet’s make a very approximate model of a human bydoas a cylinder that is h = 1.5m high and r = 0.3m in radius. a) Find the surface area of the cylinder. (Hint: the formula is A = 2(pie)rh) b) Average human body temperature is 98.6F. Convert this to Kelvin. c) Assume that this cylindrical body radiates as a blackbody at human body tem- perature. Use the Stephan-Boltzmann law to find the amount of power it radiates. d) Find the total amount of energy in Joules that the body radiates per day. e) Convert this energy to Calories (recall that 1 Calorie = 1000 calories).

Is Brody West coming back to film any time soon?
Brody West has a new scene scheduled to come out the end of April. You can look forward to seeing it via our Fratboy studio line.
