V = π × r² × t
V = 22/7 × 7² × (7 × 4)
V = 22/7 × (7 × 7) × 28
V = 22/7 × 49 × 28
V = 22/7 × 1.372
V = 30.184/7
V = 4.312 cm³
Diketahui :
Sebuah tabung
Jari jari (r) = 7 cm
Tinggi (t) = 4 kali dari r
t = 4 × 7
t = 28 cm
Ditanya :
Volume = ?
Jawab :
V = π × r × r × t
V = 22/7 × 7 × 7 × 28
V = 22 × 7 × 28
V = 154 × 28
