Diketahui:
- jari jari alas 49 cm
- tinggi 10 cm
Ditanya:
- volume tabung?
Jawab:
v = pi × r² × t
v = 22/7 × 49² × 10
v = 22/7 × 2401 × 10
v = 22 × 343 × 10
v = 22 × 3430
v = 75.460 cm³
- v tabung = πr² × t
- v tabung = 22/7 × 49 × 49 × 10
- v tabung = 22 × 7 × 49 × 10
- v tabung = 154 × 490
- v tabung = 75.460 cm³
