r2 = 6 cm
rumus volum bola = 4/3 πr³
ditanya V1 : V2
Dijawab
V1 : V2 =
4/3 π.r1³ : 4/3 π.r2³ =
4/3 π.4³ : 4/3 π.6³
coret kiri kanan sehingga
4³ : 6³ = 64 : 216 = 8 : 27 = V1 : V2 = perbandingan volume kedua bola
Maka,
Volum bola 1 : Volum bola 2
(4/3 x π x 4^3 ) : (4/3 x π x 6^3) <---- (yg sama dicoret)
4^3 : 6^3
64 : 216
8 : 27
Jadi perbandingan volume nya adalah 8 : 27
