A thief plans to steal a gold sphere with a radius of 28.5 cm from a museum. if the gold has a density of 19.3 g/cm3, what is the mass of the sphere in pounds? [the volume of a sphere is v=(4/3)πr3.]
Calculate the volume of the sphere by substituting the radius
on the given equation. The volume would be 96966.83 cm3. Then multiply the
volume with the given density which is 19.3 g/cm3. Convert the mass obtained by
dividing it with 453.592 g (1 lb = 453.592 g). The answer would be 4125.87 lb.
