d1 = 2 x d2
d2 = (1/2) x d1
d2 = 7/2 cm
t1 = t2
t1 + t2 = 16 cm
2 x t2 = 16
t2 = 16/2
t2 = 8 cm
jadi, t1 = t2 = 8 cm
volume tabung 2 = 1/4 x π x (d2)² x t2
= 1/4 x 22/7 x (7/2)² x 8
= 1/4 x 22/7 x 49/4 x 8
= 77 cm³
volume tabung 1 = 1/4 x π x (d1)² x t1
= 1/4 x 22/7 x 7² x 8
= 1/4 x 22/7 x 49 x 8
= 308 cm³
volume keseluruhan = 77 + 308
= 385 cm³
