suatu kerucut memiliki jari jari 14 cm dan tinggi 12 cm, maka volumenya adalah.....cm³
tolong ya kak ![]()
tolong ya kak
Jawaban:
Volume :
- = 1/3 × LA × t
- = 1/3 × πr² × t
- = 1/3 × 22/7 × 14² × 12
- = 1/3 × 22/7 × 196 × 12
- = 1/3 × 22 × 28 × 12
- = 1/3 × 616 × 12
- = 616 × 12/3
- = 616 × 4
- = 2.464 cm³
Penyelesaian soal :
- Volume Kerucut
[tex] \sf v = \frac{1}{3} \times \pi \times {r}^{2} \times t[/tex]
[tex] \sf = \frac{1}{3} \times \frac{22}{7} \times {14}^{2} \times 12[/tex]
[tex] \sf = \frac{1}{3} \times \frac{22}{7} \times 196 \times 12[/tex]
[tex] \sf = \frac{1}{3} \times \frac{22}{ \bcancel7} \times \bcancel{ 196 }\times 12[/tex]
[tex] \sf = \frac{1}{3} \times 22 \times 28 \times 12[/tex]
[tex] \sf = \frac{1}{ \bcancel3} \times 22 \times 28 \times \bcancel{ 12}[/tex]
[tex] \sf = 1 \times 22 \times 28 \times 4[/tex]
[tex] \sf = 22 \times 28 \times 4[/tex]
[tex] \sf = 616 \times 4[/tex]
[tex] \sf = 2.464 \: cm {}^{3} [/tex]
