Density and pressure — practice question

A micrometer screw gauge is used to measure the diameter of a solid metal sphere. The diagram gives a magnified view of the shaft of the micrometer screw gauge as the measurement is being taken. The sphere has a mass of $0.450\,\text{g}$. What is the density of the metal from which the sphere is made?

  • A$965\,\text{kg m}^{-3}$
  • B$1340\,\text{kg m}^{-3}$
  • C$7720\,\text{kg m}^{-3}$
  • D$10\,700\,\text{kg m}^{-3}$
