The density of ball weighing 0,5 kg and diameter 10 cm is....
abcdefg1234567
We know if radii = 1/2 dia r = 10/2 r = 5 cm
The ball volume formula is 4/3 phi r r r
= 4 3,14 5 5 5 / 3 = 523,59877 cm3, make it simple = 523,6 cm3 Then I change 5 kg to 5000 gram (its equal, of course). Density or Rho in greek (similar with letter p, lets use p) formula is mass/volume
p = 5000 g / 523,6 cm3 p = 9,54927 gram / cm3 (make it easy as pie) p = 9,55 gram / cm3
r = 10/2
r = 5 cm
