Volume kerucut 1
= ⅓ × Luas alas × tinggi
= ⅓ × (π × r²) × 36
= (3,14 × 16²) × 12
= (3,14 × 256) × 12
= 803,84 × 12
= 9.646,08 cm³
Volume kerucut 2
= ⅓ × (π × r²) × 42
= (3,14 × 16²) × 14
= 803,84 × 14
= 11.253,76 cm³
Volume gabungan
= Volume kerucut 1 + volume kerucut 2
= 9.646,08 + 11.253,76
= 20.899,84
= 20.900 cm³
Jadi, tidak ada jawaban yang benar
