V bangun
= V kerucut + 1/2 × V bola
= 1/3 × phi × r^2 × t + 1/2 × 4/3 × phi × r^3
= 1/3 × phi × r^2 × t + 2/3 × phi × r^3
= 1/3 × 3,14 × (6 cm)^2 × 10 cm + 2/3 × 3,14 × (6 cm)^3
= 1/3 × 3,14 × 360 cm^3 + 2/3 × 3,14 × 216 cm^3
= 1/3 × 1.130,4 cm^3 + 2/3 × 678,24 cm^3
= 376,8 cm^3 + 452,16 cm^3
= 828,96 cm^3
