Hitunglah volume bola yang berdiameter 21 cm dan π = 22/7.

MAPEL = MATEMATIKA
KELAS = 9
BAB = BRSL

diketahui =
diameter = 21cm
π = 22/7

ditanya =
V. bola?

V. bola = ⅛ × 4/3πd³
V. bola = ⅛ × 4/3 × 22/7 × 21 × 21 × 21
V. bola = ½ × 22 × 3 × 7 × 21
V. bola = 11 × 3 × 7 × 21
V. bola = 4.851 cm³

semoga membantu
