Tolong ya.. yang biasa mtk besok dikumpul,pakai cara

Answer 1

Volume tabung =phi × r^2 × t

volume tabung besar = 22/7 × 5 × 5 × 14 = 1100
volume tabung kecil = 22/7 × 3,5 ×3,5 × 10 = 385

selisih = 1100-385 = 715 (c)

Answer 2

V.tabung1=πr²t
=22/7×5×5×14
=1100 cm³
V.tabung2=πr²t
=22/7×3,5×3,5×10
=385 cm³
Selisih=1100-385=715 cm³
