Jawab:
≈ 78.571 ³/₇ cm³
Penjelasan dengan langkah-langkah:
Diketahui tabung dengan
jari-jari (r) = 25 cm
tinggi (t) = 40 cm
π ≈ ²²/₇
Ditanya volume (vol)
vol = π × r × r × t
vol ≈ ²²/₇ × 25 × 25 × 40
maka
vol ≈ ²²/₇ × 625 × 40
vol ≈ ²²/₇ × 25.000
vol ≈ 22 × ²⁵⁰⁰⁰/₇
vol ≈ 22 × (²⁴⁹⁹⁷/₇ + ³/₇)
vol ≈ 22 × (3.571 + ³/₇)
vol ≈ (22 × 3.571) + (22 × ³/₇)
vol ≈ 78.562 + (⁶⁶/₇)
vol ≈ 78.562 + (⁶³/₇ + ³/₇)
vol ≈ 78.562 + 9 + ³/₇
vol ≈ 78.571 + ³/₇
vol ≈ 78.571 ³/₇ cm³
