Jawab:
Volume = 13141.3 cm³
Penjelasan dengan langkah-langkah:
1. Volume tabung = πr² × t
jari-jari (r) = 28:2=14 cm
tinggi (t) = 20 cm
V= πr²×t
V= 22/7 × 14 × 14 × 20
V= 12320 cm³
2. Volume kerucut = 1/3 × L alas × t
tinggi kerucut = 24-20 = 4cm
V = 1/3 × πr² × t
V = 1/3 × (22/7 × 14 × 14) × 4
V = 1/3 × 616 × 4
V = 821.3 cm³
3. Kesimpulan:
V tabung + V kerucut
12320 + 821.3 = 13141.3 cm³
