sebuah kerucut dengan tinggi 10 cm dan jari jari 2cm
![]()
Volume kerucut = 1/3 phi x r kuadrat x t
= 1/3 x 3,14 x 2 x 2 x 10
= 125,6/3
= 41,86
Jawaban :
t = 30 cm
r = 2 cm
[tex]v \: = \frac{1}{3} \times \pi {r}^{2} \times t \\ v \: = \frac{1}{3} \times ( \: 3.14 \times 2 \times 2 \times 30 \: ) \\ v \: = \frac{1}{3} \times 376.8 \\ v \: = 125.6 \: {cm}^{3} \\ v \: = 125.6 \: {dm}^{3} \\ v \: = 125.6 \: liter [/tex]
Semoga membantu
