Jawaban:
langkah 1, cari dulu tinggi kerucut
t² = s² - r² (Pythagoras)
t² = 13² - 5²
t² = 169 - 25
t² = 144
t = √144
t = 12 cm
langkah 2, hitung volume tiap bangun
V kerucut = ⅓ × πr² × t
= ⅓ × 3,14 × 5² × 12
= 314 cm³
V tabung = πr² × t
= 3,14 × 5² × 12
= 942 cm³
V ½ bola = ½ × 4/3 × πr³
= ⅔ × 3,14 × 5³
= 261,67 cm³
V gabungan = 314 + 942 + 261,67
= 1.517,67 cm³
Semoga membantu ya...
