r = [tex]\rm{\sqrt{s^{2} - t^{2}}}[/tex]

r = [tex]\rm{\sqrt{13^{2} - 12^{2}}}[/tex]

r = [tex]\rm{\sqrt{169 - 144}}[/tex]

r = [tex]\rm{\sqrt{25 }}[/tex]

r = [tex]\rm{5 \: cm}[/tex]

Volume kerucut

V = 1/3 × Ο€ × r² × t

V = 1/3 × 3,14 × 5² × 12

V = 1/3 × 3,14 × (5 × 5) × 12

V = 1/3 × 3,14 × 25 × 12

V = 1 × 3,14 × 25 × 4

V = 3,14 × 100

V = 314 cm³

Diketahui

  • T ➡ 13 cm
  • s ➡ 12 cm

Ditanya

r =√s²- t²

=√13² - 12²

=√169 - 144

=√25

=5

[tex]v = \frac{1}{3} \times \pi \times r {}^{2} \times t[/tex]

[tex] \: \: \: \: = \frac{1}{3} \times 3.14 \times 5 {}^{2} \times 13[/tex]

[tex] \: \: \: \: = 314 \: cm {}^{3} [/tex]

Kesimpulan

Jadi, volume kerucut tersebut adalah 314 cm³
