Jawab:
bangun ruang
bola didalam tabung
Penjelasan dengan langkah-langkah:
d bola = d alas tabung = 42
r bola = r alas tabung = 1/2 (d) = 1/2 (42) = 21
t tabung = d bola = 2(r) = 42
Volume udara = V tabung - v bola
Vudara = π r² t - 4/3 π r³
V udara = π r² ( t - 4/3 r)
V udara = 22/7. 21² ( 42 - 4/3 (7))
V u = 1.386 (42 - 28/3)
V u = 32 ²/₃
