Volume tabung pada gambar di bawah ino adalah…cm³.
`Bangun ruang
• Tabung
d = 21 cm
r = d/2
r = 21/2
r = 10,5 cm
t = 25 cm
Volume tabung
V = π × r² × t
V = 22/7 × (10,5)² × 25
V = 22/7 × (10,5 × 10,5) × 25
V = 22/7 × 110,25 × 25
V = 22/7 × 2.756,25
V = 22 × 393,75
V = 8.662,5 cm³
d = 21 cm
r = d/2
r = 21/2
r = 10,5 cm
___
V = πr²t
V = 3,14 × 10,5² × 25
V = 3,14 × 110,25 × 25
V = 346,185 × 25
V = 8.654,625 cm³
