Compute each part of given question:
Question: Gold, which has a density of 19.32 g/cm3, is the most ductile metal and can be pressed into a thin leaf or drawn out into a long fiber.
Part A: If a sample of gold with a mass of 4.565 g, is pressed into a leaf of 6.249 m thickness, what is the area of the leaf?
Part B: If, instead, the gold is drawn out into a cylindrical fiber of radius 2.000 m, what is the length of the fiber?
