Jika tinggi kerucut 8cm dan diameter bola 12cm,maka volume bangun adalah

Volume Kerucut :
V = ⅓ × π × r × r × t
V = ⅓ × 3,14 × (12/2) × (12/2) × 8
V = ⅓ × 3,14 × 6 × 6 × 8
V = 3,14 × 2 × 6 × 8
V = 3,14 × 12 × 8
V = 3,14 × 96
V = 301,44 cm³

Volume ½ Bola :
V = ½ × 4/3 × π × r × r × r
V = ½ × 4/3 × 3,14 × 6 × 6 × 6
V = ½ × 4 × 3,14 × 2 × 6 × 6
V = ½ × 12,56 × 12 × 6
V = ½ × 12,56 × 72
V = ½ × 904,32
V = 452,16 cm³

Volume Gabungan :
V = 452,16 cm³ + 301,44 cm³
V = 753,6 cm³
