Tentukan Volume Gabungan Bangun Ruang berikut
Volume Gabungan
Diketahui
= 2 × V. Kerucut + V. Tabung
= 2 × ⅓ × Ο × r³ × tk + 22/7 × r² × tt
Ο = 22/7
r = 7 Cm.
tk = 25 Cm.
tt = 20 Cm.
Volume Gabungan
= 2 × ⅓ × 22/7 × 7² × 25 + 22/7 × 7² × 20
= 2 × ⅓ × 22/7 × 49 × 25 + 22/7 × 49 × 20
= 2.566,67 + 3080
= 5.646,67 Cm³.
