Sagot :
V = 4xPixr^3/3 = 4xPix(6,4x10^6)^3/3 = 1,1x10^21 mcube
p = m/V = 6x10^24/1,1x10^21 = 5455 kg/mcube
p = m/V = 6x10^24/1,1x10^21 = 5455 kg/mcube
je pense que c'est ça : V = 4xPixr^3/3 = 4xPix(6,4x10^6)^3/3 = 1,1x10^21 mcube
p = m/V = 6x10^24/1,1x10^21 = 5455 kg/mcube
p = m/V = 6x10^24/1,1x10^21 = 5455 kg/mcube
