Diketahui :
- r = 10 cm
- t = 18 cm
Ditanya :
Volume kerucut?
Dijawab :
V = 1/3 × π × r² × t
V = 1/3 × 3,14 × 10² × 18
V = 1/3 × 3,14 × (10 × 10) × 18
V = 1/3 × 3,14 × 100 × 18
V = 1/3 × 314 × 18
V = 1/3 × 5.652
V = 5.652/3
V = 1.884 cm³
V kerucut= ⅓ × (phi × r²) × t
= ⅓ × (3,14 × 10²) × 18
= ⅓ × 314 × 18
= 1.884
