The property that compares the mass of an object with its volume is density.
Answer: 4 x 106
That’s how you write forty million in scientific notation.
Vol of sphere = 4/3 pi r^2.density of sphere = mass/volume.mass = densityxvolumesphere 1. mass = density x 4/3 pi 4.5^2sphere 2 5mass = density x 4/3 pi r^25=4/3 pi r^2 divided by 4/3 pi 4.5^25=r^2 divided by 4.5^25x4.5^2=r^2root(5x4.5^2)=r4.5 root 5 = r
The answer would be B.
(V=IR, 12-10i, 12/10=1.2)
