4.
Volume Kerucut :
V = ⅓ × π × r × r × t
V = ⅓ × 3,14 × (20/2) × (20/2) × 48
V = 3,14 × 10 × 10 × 16
V = 314 × 16
V = 5.024 cm³

5.
Volume Balok :
V = p × l × t
V = 2,5 m × 20 cm × 15 cm
V = 25 dm × 2 dm × 1,5 dm
V = 50 dm² × 1,5 dm
V = 75 dm³
V = 75 liter

Maaf Kalau Salah

1. v = La x t
v = 3,14 x r x r x t x 1/3 cm
v = 3,14 x 10 x 10 x 1/3 cm
v = 314 x 1/3 xm
v = 104 ,6666666....... cm3

2. v = p x l xt
v = 250 x 20 x 15 cm
v = 5000 x 15 cm
v = 75000 cm3
v = 7500 liter
