Tolong ya bantuin pake cara besok dikumpulin ya nomer 1-4

Answer 1

Verified answer

1) volume = r³
= 100 × 100 × 100 cm
= 1.000.000 cm³
= 1.000 liter
debit = 1 liter/ mnt
waktu = 100 liter ÷ 1 liter/mnt
= 100 mnt
= 1 ⅔ jam

2) L1 = p × l = 28 × 22 = 616 cm²
L2 = ½ × π × r² = ½ × 22/7 × 14 × 14 = 308 cm²
Lttl = L1 + L2 = 616 + 308 = 924 cm²

3) L1 = a × t = 24 × 15 = 360 cm²
L2 = ½ × a × t = ½ × 24 × 25 = 300 cm²
L3 = ½ × π × r² = ½ × 3,14 × 10 × 10 = 157 cm²
Lttl = 360 + 300 + 157 = 817 cm²

4) Volume = La × t
= ½ × 5 × 12 × 20
= 600 cm³
