Jika volume tabung 396cm berapakah volume didalam tabung tersebut

Volume tabung =396 cm³
Tinggi tabung = diameter bola =2×r

Volume tabung
= phi x r x r x t
= phi x r x r x 2r
= 2×phi x r³

Volume bola = 4/3 ×phi x r³
(Volumr tabung) : ( volume bola) =
(2×phi x r³) : (4/3 ×phi x r³)

Volume bola
=[ (4/3 ×phi x r³) / (2×phi x r³) ] × 396
= 4/3 ×1/2×396
=2/3 ×396
= 2× 132
=264 cm³
