3500J / s of energy is transferred from a heat source to the surface of the part. The heated region is circular and the heat density decreases as the radius increases. Find out whether the heat density is sufficient to melt the metal since 70% of the heat is concentrated in a circle with a diameter of 3.75 mm.
