Part D:What is the thickness of the air layer (contained within the fur), L air? Express your answer in meters.Part E:How many inches (L fur) should the fur layer be to hold a layer of air L air thick so that adequate insulation is provided? Express your answer numerically in inches..

Review | Constants What is the surface area A of the layer of fat? Express your answer numerically in meters squared. Learning Goal: View Available Hint(s) Animals in cold climates often depend on two layers of insulation: a layer of body fat (of thermal conductivity 0.200 W / (m . K) ) surrounded by a layer of air trapped inside fur or down. We can model a black bear ( Ursus VO AEQ americanus) as a sphere 1.50 m in diameter having a layer of fat 4.00x10-2 m thick, as shown in the figure.( m Figure 1) (Actually, the thickness varies with the season, but we are interested in hibernation, when the fat layer is Submit Figure
