Question

Tentukan volume gabungan bangun ruang sesuai gambar tersebut

tolong dijawab pake cara​

Answer 1

Penjelasan dengan langkah-langkah:

volume kerucut

[tex] \frac{1}{3} \times a \times t \\ [/tex]

volume tabung

[tex]a \times t[/tex]

maka

Volume kerucut

[tex] = \frac{1}{3} \times \pi {r}^{2} \times t \\ = \frac{1}{3} \times 3.14 \times {6}^{2} \times 8 \\ = \frac{1}{3} \times 3.14 \times 36 \times 8 \\ = \frac{1}{3} \times 3.14 \times 288 \\ = \frac{1}{3} \times 904.32 \\ = 301.44 \: {cm}^{3} [/tex]

Volume tabung

[tex] = \pi {r}^{2} \times t \\ = 3.14 \times {6}^{2} \times 10 \\ = 3.14 \times 36 \times 10 \\ = 3.14 \times 360 \\ = 1,130.4 \: {cm}^{3} [/tex]

maka total volume

= 301,44 + 1130,4

= 1431,84 cm³
