Jawaban:
Volume Tabung~
V = π × r × r × t
V = 3,14 × 10 × 10 × 14
V = 3,14 × 100 × 14
V = 3,14 × 1.400
V = 4.396cm³
Volume Kerucut~
V = ⅓ × π × r × r × t
V = ⅓ × 3,14 × 10 × 10 × 14
V = ⅓ × 3,14 × 100 × 14
V = ⅓ × 3,14 × 1.400
V = 1.465cm³
Gabungan~
V = Tabung + Kerucut
V = 4.396 + 1.465
V = 5.861 cm A³
