volume kerucut tersebut adalah

4.312.000 liter

Pembahasan

Diketahui: Mencari volume kerucut: V kerucut = = = = = = 3 1 π r 2 t 3 1 ⋅ 7 22 ⋅ 1 4 2 ⋅ 21 3 1 ⋅ 7 22 ⋅ 196 ⋅ 21 21 22 ⋅ 196 ⋅ 21 3 616 ⋅ 21 4.312 m 3 Karena 1 m 3 = 1.000 liter , maka ketika dikonversi menjadi liter: Volume kerucut = = 4.312 × 1.000 4.312.000 liter Jadi,volume kerucut tersebut adalah 4.312.000 liter .

Mencari volume kerucut:

$V kerucut = = = = = = \frac{1}{3} π r^{2} t \frac{1}{3} \cdot \frac{22}{7} \cdot 1 4^{2} \cdot 21 \frac{1}{3} \cdot \frac{22}{7} \cdot 196 \cdot 21 \frac{22}{21} \cdot 196 \cdot 21 \frac{616}{3} \cdot 21 4.312 m^{3}$
