The heat capacity of lead is C = .127.10^3J/kg*K (I googled it) So the heat capacity of the bullet is Cm=.635 J/K The kinetic energy of your bullet is KE = 1/2*5.10^-3 250^2 J Therefore the increase in temp will be 1/2KE/(Cm) = 123 degrees

144 = (3.14)(x+4)^2 144/3.14 = (x+4)^2 45.86 = x^2 + 16 45.86 - 16 = x^2 29.86 = x^2 square root both sides and you get x = 5.46
