Penjelasan dengan langkah-langkah:
4. d = 14 dm
r = 1/2 . d
r = 1/2 . 14
r = 7 dm
t = 2 m = 20 dm
v = π x r² x t
v = 22/7 x 7 x 7 x 20
v = 3.080 cm³
w = v/d
w = 3.080 liter/(7 liter/menit)
w = 440 menit
w = 440 x 60
w = 26.400 detik
5. v = 5.000 dm³
d = 2 m
r = 1/2 . 2
r = 1 m = 10 dm
5.000 = 3,14 x 10 x 10 x t
5.000 = 314 x t
t = 5.000 : 314
t ≈ 15,9 dm
t = 16 dm
t = 1,6 m
ps. krn t tidak genap dibagi, maka dibulatkan
