jgn ngasal yaa,jawab dgn caranya!
Jari - Jari (Kerucut & Bola)
= 12 ÷ 2
= 6 cm
Tinggi Kerucut
= 18 - Jari - Jari Bola
= 18 - 6
= 12 cm
Volume Kerucut
= ⅓ × πr² t
= ⅓ × π × 6² × 12
= 4 × π × 36
= 144π
Volume ½ Bola
= ½ × 4/3 × π × r³
= 2/3 × π × 6³
= 2 × 2 × π × 6²
= 4 × 36 × π
= 144π
Volume Gabungan
= 144π + 144π
= 288π cm³
