143,916 cm³
Penjelasan dengan langkah-langkah:
Volume kerucut:
V = 1/3 × π × r² × t
V = 1/3 × 3,14 × 5 × 15
V = 1/3 × 3,14 × 75
V = 1/3 × 235,5
V = 235,5/3
V = 78,5 cm³
Volume ½ bola:
V = 1/2 × 4/3 × π × r³
V = 1/2 × 4/3 × 3,14 × 5 × 5 × 5
V = 1/2 × 4/3 × 3,14 × 125
V = 1/2 × 4/3 × 392,5
V = 1/2 × 392,5/3
V = 1/2 × 130,83
V = 130,833/2
V = 65,416 cm³
Volume gabungan:
V gabungan = V kerucut + V ½ bola
V gabungan = 78,5 + 65,416
V gabungan = 143,916 cm³
Penyelesaian
Bangun gabungan,maka volume nya dijumlah saja.
V=½V bola+V kerucut
V=½(4/3πr³)+(⅓×La×t)
V=⅔×3,14×10³+⅓×3,14×10×10×15
V=⅔×3.140+314×5
V=2.093⅓+1.570
V=3.663⅓cm³
Semoga bermanfaat
