Answer 1

Jawaban:

Volume kubus :

• = s³
• = 14 × 14 × 14
• = 196 × 14
• = 2.744 cm³

Volume tabung :

• = πr² × t
• = 22/7 × (14 × 1/2)² × 14
• = 22/7 × 7² × 14
• = 22/7 × 49 × 14
• = 22 × 49 × 2
• = 1.078 × 2
• = 2.156 cm³

Volume gabungan :

• V kubus + V tabung
• = 2.744 cm³ + 2.156 cm³
• = 4.900 cm³ (Opsi A)

Answer 2

Kubus

s = 14 cm

V = s³

V = 14 cm × 14 cm × 14 cm

V = 196 cm × 14 cm

V = 2.744 cm³

Tabung

t = 14 cm

d = 14 cm

r = 14 cm ÷ 2 = 7 cm

V = π × r² × t

V = 22/7 × 7 cm² × 14 cm

V = 22/7 × 7 cm × 7 cm × 14 cm

V = 22 × 1 cm × 7 cm × 14 cm

V = 22 cm × 7 cm × 14 cm

V = 154 cm × 14 cm

V = 2.156 cm³

Gabungan

V = 2.744 cm³ + 2.156 cm³

V = 4.900 cm³

Opsi A.
