kak tolong di jawab pakai cara secepatnya ya, buru buru soal nya.
Soal 1
Volume kerucut
= ⅓ × La × t
= ⅓ × ( π × r² ) × t
= ⅓ × ( 22/7 × 7² ) × 20
= ⅓ × 154 × 20
= ⅓ × 3.080
= 1.026,67 cm³
Soal 2
Volume kerucut
= ⅓ × La × t
= ⅓ × ( π × r² ) × t
= ⅓ × ( 22/7 × 21² ) × 30
= ⅓ × 462 × 30
= ⅓ × 13,860
= 4.620 cm³
Jawaban:
[tex]1.v = \frac{1}{3} \times \pi {r}^{2} \times t[/tex]
[tex]v = \frac{1}{3} \times \frac{22}{7} \times 7 \times 7 \times 20[/tex]
[tex]v = \frac{1}{3} \times 22 \times 7 \times 20[/tex]
[tex]v = 1026.6 {cm}^{3} [/tex]
[tex]2. v = \frac{1}{3} \times \pi {r}^{2} \times t [/tex]
[tex]v = \frac{1}{3} \times \frac{22}{7} \times 21 \times 21 \times 27[/tex]
[tex]v = 22 \times 21 \times 27[/tex]
[tex]v = 12,474 {cm}^{3} [/tex]
