= massa / volume
= 0,6 / (4/3) π r³
= 0,6 / (4/3) (3,14) 5³
=9/7850
=1,146 x 10^(-3)
m = 0,6 kg,
D = 10 cm
Ditanyakan : ρ (massa jenis bola) ?
Penyelesaian :
Volume bola = 4/3 π
Volume bola = 4/3 (3,14) (5 x )^3
Volume bola = 4,1867 (1,25 X )
Volume bola = 5,23 x
Massa jenis bola = massa bola / volume bola
= 0,6 / 5,23 x
= 1147,23 kg/
