luas permukaan bola 154 cm² .jika π = 22/7 .hitung volume bola tersebut???

[tex]154 = 4 \times \frac{22}{7} \times {r}^{2} \\ 154 = \frac {88}{7} \times {r}^{2} \\ 12.25 = {r}^{2} \\ r = 3.5cm \\ \\ volume = \frac{4}{3} \times \frac{22}{7} \times 3.5 \times 3.5 \times 3.5 \\ volume = 179.67{cm}^{3} [/tex]

Maaf kalo salah, semoga membantu

L = 4πr²
r = √[L / (4π)]
  = √[154 cm² / (4 × 22/7)] = 3,5 cm

V = 4/3 πr³
   = 4/3 (22/7)(3,5 cm)³
   ≈ 179,67 cm³
