Tolong jawab ya kak :)

Volume bangun di atas = V tabung + V bola
V tabung = 3,14 × r × r x t
= 3,14 × 3 × 3 × (26 - 6)
= 3,14 × 9 × 20
= 62,8 × 9
= 565,2 cm^3

V bola = 4/3 × r x r x r
= 4/3 × 3 × 3 × 3
= 4 × 9
= 36 cm^3

V keseluruhan = 601,2 cm^3

Berat benda = 601, 2 × 8 gram
= 4809,6 gram
= 4,81 kg
