maaf kalo salah...

Jawaban:

B. 3850cm³.

Penjelasan dengan langkah-langkah:

Kerjakan satu persatu

Volume tabung.

Ubah diameter ke jari jari.

[tex]r = \frac{d}{2} \\ = \frac{14}{2} = 7cm[/tex]

Gunakan rumus

[tex]\color{cyan}V = \pi {r}^{2} t[/tex]

Maka,

[tex]V = \frac{22}{7} \times {7}^{2} \times 20 \\ = 22 \times 7 \times 20 \\ = 440 \times 7 \\ \color{cyan} = {3080cm}^{3} [/tex]

Volume kerucut.

Gunakan rumus

[tex]\color{orange}V = \frac{la \times t}{3} \\ [/tex]

Maka,

[tex]V = \frac{154 \times (35 - 20)}{3} \\ = \frac{154 \times 15}{3} \\ = 154 \times 5 \\ \color{orange}= 770cm {}^{3} [/tex]

Maka,

[tex] = \color{cyan}3080 \color{n} + \color{orange}770 \\ = \color{green}3850cm {}^{3} [/tex]
