Hitunglah volume gabungan berikut 1. Tabung =t= 18 R= 7 2. Kerucut = t = 15 R =7

Volume Tabung :
V = πr²t
V = 22/7 × 7 × 7 × 18
V = 22 × 7 × 18
V = 154 × 18
V = 2.772

Volume Kerucut :
V = ⅓πr²t
V = ⅓ × 22/7 × 7 × 7 × 15
V = 22 × 7 × 5
V = 154 × 5
V = 770

Volume Gabungan :
V = 2.772 + 770
V = 3.542

Maaf Kalau Salah

pelajaran = matematika
masalah = volume

1. volume tabung = luas alas x tinggi
= π x R² x t = 22/7 x 7² x 18 = 2772

2. volume kerucut = luas alas x tinggi
= π x R² x t = 22/7 x 7² x 15 = 2310
