Bantuin dong harus kumpul besok

Dik : Tinggi tabung = 20 - 6 = 14 cm
Jari - jari (r) = 1/2 diameter = 1/2 x 28 = 14 cm

Volume Balok = p x l x t = 28 x 28 x 6 = 4704 cm^3

Volume Tabung = (phi) r^2 t
= 22/7 x 14^2 x 14
= 8624 cm^3

Volume gabungan = Volume Balok + Volume Tabung = 4704 + 8624 = 13328 cm^3

Semoga membantu :)
