jika volume bola 300 cm², maka volume tabung adalah ... ( pake cara perbandingan ) makasih kak !!

r bola = r tabung = r
t tabung = 2×r bola = r

Volume bola = 4/3 × phi × r^3

Volume tabung = phi × r^2 × (2×r) = 2× phi × r^3

Volume bola : volume tabung = (4/3 × phi × r^3) : (2× phi × r^3) = 4/3 : 2 = 4 : 6 = 2 : 3

Volume tabung = 3/2 × 300 = 900/2 = 450 cm^3
