Jawab:
r = d/2
r = 20/2
r = 10 cm
Volume tabung = π x r² x t
Volume tabung = 3,14 x 10 x 10 x 30
Volume tabung = 9.420 cm³
tinggi kerucut = 48 cm - 30 cm
tinggi kerucut = 18 cm
Volume kerucut = x r² x t
Volume kerucut = x 10 x 10 x 18
Volume kerucut = 1.884 cm³
Volume gabungan = volume tabung + volume kerucut
Volume gabungan = 9.420 cm³ + 1.884 cm³
Volume gabungan = 11.304 cm³
Penjelasan dengan langkah-langkah:
Diketahui :
Jari² Tabung = 10cm
Tinggi Tabung = 30cm
Jari² Kerucut = 10cm
Tinggi Kerucut = 48-30 = 18cm
Ditanya :
Volume Gabungan
Rumus :
Volume Gabungan = Volume Tabung + Volume Kerucut
Volume Tabung = 3,14 x r² x t
Volume Kerucut = 3,14 x 1/3 x r² x t
Jawab :
Volume Tabung
= 3,14 x r² x t
= 3,14 x 10² x 30
= 3,14 x 100 x 30
= 9.420cm³
Volume Kerucut
= 3,14 x 1/3 x r² x t
= 3,14 x 1/3 x 10² x 18
= 3,14 x 100 x 6
= 1.884cm³
= Volume Tabung + Volume Kerucut
= 9.420 + 1.884
= 11.304cm³
