Jawaban:
volume tabung :
V = πr² x t
V = 3,14 (9cm)² x 15cm
V = 3,14 x 81cm² x 15cm
V = 3815,1 cm³
volume bola :
V = 4/3 πr³
V = 4/3 . 3,14 (9cm)³
V = 4/3 . 3,14 x 729cm³
V = 4. 3,14 x 243cm³
V = 12,56 x 243cm³
V = 3052,08 cm³
volume total :
V tabung + V bola
= 3815,1 cm³ + 3052,08 cm³
= 6867,18 cm³ (C)
