tolong di bantu ya kak makasih ya ​

Answer 1

Verified answer

[tex]volume \: balok + \frac{1}{2} \: tabung \\ \\ p \times l(t + \frac{l}{8} \pi) \\ \\ 20 \times 14(10 + \frac{14}{8} \times \frac{22}{7} ) \\ \\ 280(10 + 5,5) \\ \\ 280(15,5) \\ \\ 4.340 \: {cm}^{3} [/tex]

Answer 2

Jawaban:

Penyelesaian :

• Panjang balok = 20 cm
• Lebar balok = 14 cm
• Tinggi balok = 10 cm
• Jari - jari tabung = 14 : 2 = 7 cm
• Tinggi tabung = 20 cm

Volume gabungan

Volume balok :

V = p × l × t

V = 20 × 14 × 10

V = 20 × 140

V = 2.800 cm³

.

Volume ½ tabung

V = ½ × (π × r² × t)

V = ½ × (22/7 × 7² × 20)

V = ½ × (22/7 × 49 × 20)

V = ½ × (22 × 7 × 20)

V = ½ × 3.080

V = 1.540 cm³

.

Volume gabungan balok & Volume ½ tabung

Volume gabungan = Vbalok + V½tabung

Volume gabungan = 2.800 + 1.540 cm³

Volume gabungan = 4.340 cm³
