A. 2.414 cm³
B. 1.500 cm³
C. 2.400 cm³
D. 2.15 cm³
Penjelasan dengan langkah-langkah:
diamenter tabung = 14 cm
rusuk tabung = Diameter : 2
rusuk tabung = 14 : 2
rusuk tabung = 7 cm
-------
- Volume Tabung
[tex]\tt\color{blue} = πr²t [/tex]
[tex]\tt\color{blue} = 22/7 × 7² × 12 [/tex]
[tex]\tt\color{blue} = 22/7 × 7 × 7 × 12 [/tex]
[tex]\tt\color{blue} = 22/7 × 49 × 12 [/tex]
[tex]\tt\color{blue} = 22 × 49/7 × 12 [/tex]
[tex]\tt\color{blue} = 22 × 7 × 12 [/tex]
[tex]\tt\color{blue} = 22 × 84 [/tex]
[tex]\tt\color{blue} = 1.848 cm³ [/tex]
- Volume Kerucut
[tex]\tt\color{blue} = 1/3 × π × r² × t [/tex]
[tex]\tt\color{blue} = 1/3 × 22/7 × 7² × 12 [/tex]
[tex]\tt\color{blue} = 1/3 × 22/7 × 7 × 7 × 12 [/tex]
[tex]\tt\color{blue} = 1/3 × 22/7 × 49 × 12 [/tex]
[tex]\tt\color{blue} = 1/3 × 22 × 294/7 [/tex]
[tex]\tt\color{blue} = 1/3 × 22 × 42 [/tex]
[tex]\tt\color{blue} = 1/3 × 924 [/tex]
[tex]\tt\color{blue} = 308 cm³ [/tex]
- Volume Gabungan
[tex]\tt\color{blue} = Volume tabung + Volume Kerucut [/tex]
[tex]\tt\color{blue} = 1.848 cm³ + 308 cm³ [/tex]
[tex]\tt\color{blue} = (1.848 + 308) cm³ [/tex]
[tex]\tt\color{blue} = 2.156 cm³ [/tex]
semoga membantu
- Volume tabung
→ πr²t
→ [tex]\tt \frac{22}{7}[/tex] × 7² × 12
→ [tex]\tt \frac{22}{7}[/tex] × 49 × 12
→ 22 × 7 × 12
→ 154 × 12
→ 1.848 cm³
- Volume kerucut
→ [tex]\tt \frac{1}{3}[/tex]πr²t
→ [tex]\tt \frac{1}{3}[/tex] × [tex]\tt \frac{22}{7}[/tex] × 7² × 6
→ [tex]\tt \frac{1}{3}[/tex] × [tex]\tt \frac{22}{7}[/tex] × 49 × 6
→ [tex]\tt \frac{1}{3}[/tex] × [tex]\tt \frac{22}{7}[/tex] × 294
→ [tex]\tt \frac{1}{3}[/tex] × 22 × 42
→ [tex]\tt \frac{1}{3} [/tex] × 924
→ 308 cm³
- Volume gabungan
→ Volume tabung + volume kerucut
→ 1.848 + 308
→ 2.156 cm³
