1) Iron in the asteroid 16 Psyche is said to be valued at 8973 quadrillion euros (EUR), where one quadrillion 10¹5. James believes the asteroid is approximately spherical with radius 113 km. He uses this information to estimate its volume. a) Write down the value of the iron in the form a x 10k where 1 < a < 10, keZ. b) Calculate James's estimate of its volume, in km³. c) The actual volume of the asteroid is found to be 6.074 x 106 km³. Find the percentage error in James's estimate of the volume.
