Rumus Volume Tabung
Rumus: π × r² × t
Input:
Jari-jari (r) = 5 cm
Tinggi (t) = 12 cm
Perhitungan:
Volume = π × 5² × 12
Volume = 3.1416 × 25 × 12
Volume = 78.54 × 12
Hasil:
Volume Tabung = 942.48 cm³
Bonus: Luas Permukaan Tabung
Rumus: 2π × r × (r + t)
Luas Permukaan = 2π × 5 × (5 + 12)
Luas Permukaan = 2π × 5 × 17
Luas Permukaan = 534.07 cm²
Informasi Tabung:
• Diameter = 2 × jari-jari = 10 cm
• Keliling alas = 2π × r = 31.42 cm
• Luas alas = π × r² = 78.54 cm²
