hitunglah volume bola berikut r=7
![]()
Jawaban:
[tex] \frac{1}{2} \times \frac{4}{3} \times \frac{22}{7} \times {7}^{3} \\ = 718.67 {cm}^{3} [/tex]
r = 7 satuan
Volume bola
V = 4/3 × Ο × r³
V = 4/3 × 22/7 × 7³
V = 4/3 × 22/7 × (7 × 7 × 7)
V = 4/3 × 22/7 × 343
V = 4/3 × 22 × 49
V = 4/3 × 1.078
V = 4.312/3
V = 1.437,33 satuan kubik
