Diketahui : - Diameter Tabung (d) = 21 cm - Tinggi Tabung (t) = 28 cm
Ditanya : - Volume Tabung (V) = .....?
Penyelesaian : - Volume Tabung (V) : V = ¼ × π × d × d × t V = ¼ × 22/7 × 21 cm × 21 cm × 28 cm V = 22/7 × 21 cm × 21 cm × 7 cm V = 22 cm × 21 cm × 21 cm V = 22 cm × 441 cm² V = 9.702 cm³

Diketahui :
- Diameter Tabung (d) = 21 cm
- Tinggi Tabung (t) = 28 cm
Ditanya :
- Volume Tabung (V) = .....?
Penyelesaian :
- Volume Tabung (V) :
V = ¼ × π × d × d × t
V = ¼ × 22/7 × 21 cm × 21 cm × 28 cm
V = 22/7 × 21 cm × 21 cm × 7 cm
V = 22 cm × 21 cm × 21 cm
V = 22 cm × 441 cm²
V = 9.702 cm³
Jawaban : D. 9.702 cm³

R = 21 cm : 2 = 10.5
T = 28 cm
Dit :
V = .. ?
Jawab :
V = phi x r x r
= 22/7 x 10,5 x 10,5x 28
= 9.702 cm³
