Kak tolong bantu jawab besok di pumpulin Dikasih diketahui nya

<p>Diketahui :</p><p>r = 7 cm</p><p>Tinggi tabung = 12 cm</p><p>Tinggi total (tinggi tabung + kerucut) = 36 cm</p><p>&nbsp;</p><p>Ditanya :</p><p>Volume gabungan =</p><p>&nbsp;</p><p>Jawab :</p><p>Tinggi kerucut = tinggi total - tinggi tabung</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 36 - 12</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 24 cm.&nbsp;</p><p>&nbsp;</p><p>Volume total = volume kerucut + volume tabung</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = &nbsp;⅓ × π × r² × tinggi kerucut +π × r² × tinggi tabung</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = ⅓ × 22/7 × 7 × 7 × 24 + 22/7 × 7 × 7 × 12</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = 22 × 7 × 8 + 22 × 7 × 12</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 154 × 8 + 154 × 12</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 1220 + 1860</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 3080 cm³</p><p>Jadi, volume gabungan adalah 3080 cm³</p>
