tolong dijawab ya kak no.8

Mapel : Matematika
Bab : Bangun Ruang Sisi Lengkung

d = 14 cm
r = 7 cm
t tabung = 20 cm
t kerucut = 44 cm - 20 cm = 24 cm

Volume gabungan
= Volume tabung + Volume kerucut
= π x r² x t + 1/3 x π x r² x t
= 22/7 x 7 cm x 7 cm x 20 cm + 1/3 x 22/7 x 7 cm x 7 cm x 24 cm
= 3.080 cm³ + 1.232 cm³
= 4.312 cm³
