plis tolong bantu ya kk kalo benar aku jadiin jawaban tercerdas ya kk
1. Volume Tabung = 34.650 cm³
2. Volume Tabung = 3.089 cm³
3. Volume Tabung = 2.260,8 cm³
4. Volume Tabung = 172.480 cm³
Penjelasan dengan langkah-langkah:
1. Diketahui:
Jari - jari (r) = 21 cm
Tinggi (t) = 25 cm
π = 22/7
Penyelesaian:
Volume Tabung
= πr²t
= 22/7 × 21² × 25
= 22/7 × 441 × 25
= 22 × 63 × 25
= 34.650 cm³
2. Diketahui:
Jari - jari (r) = 7 cm
Tinggi (t) = 20 cm
π = 22/7
Penyelesaian:
Volume Tabung
= πr²t
= 22/7 × 7² × 20
= 22/7 × 49 × 20
= 22 × 7 × 20
= 3.080 cm³
3. Diketahui:
Jari - jari (r) = 6 cm
Tinggi (t) = 20 cm
π = 3,14
Penyelesian:
Volume Tabung
= πr²t
= 3,14 × 6² × 20
= 3,14 × 36 × 20
= 2.260,8 cm³
4. Diketahui:
Jari - jari (r) = 28 cm
Tinggi (t) = 70 cm
π = 22/7
Penyelesaian:
Volume Tabung
= πr²t
= 22/7 × 28² × 70
= 22/7 × 784 × 70
= 22 × 784 × 10
= 172.480 cm³
