volume belahan bola = 1/2 x 4/3 x phi x r kubik
r = 12 : 2 = 6
v = 1/2 x 4/3 x 3,14 x 6 x 6 x 6
= 2 x 3,14 x 2 x 6 x 6
= 3,14 x 144
= 452,16
maaf kalau salah, semoga membantu :)
= 12 cm : 2
= 6 cm
V = 1/2 × 4/3 × π × r³
= 1/2 × 4/3 × 3,14 × 6³
= 2/3 × 3,14 × 216
= 2/3 × 678,24
= 2 × 226,08
= 452,16 cm³
Jadi volume benda tersebut adalah 452,16 cm³
