t = 51
r = 42/2 = 21 cm
V = 1/3πr²t
V = 1/3 × 22/7 × 21 × 21 × 51
V = 22 × 3 × 21 × 17
V = 66 × 21 × 17
V = 1.386 × 17
V = 23.562 dm³ = 23.562 liter
Penjelasan dengan langkah-langkah:
V kerucut = ⅓πr²t
[tex] \frac{1}{3} \times \frac{22}{7} \times 21 \times 21 \times 51[/tex]
= 23.562 cm³ atau 23.562 liter
semoga membantu
