1. v = π × r² × t
= 22/7 × 14² × 20
= 22/7 × 196 × 20
= 22/7 × 3.920
= 12.320 cm³

2. v = π × r² × t
5.652 = 3,14 × r² × 18
5.652 = 56,52 × r²
r² = 5.652 : 56,52
r = √100
r = 10 cm
3. V total = V air + V kubus
= ( π × r² × t ) + ( s × s × s )
= (22/7×7²×10) + ( 2 × 2 × 2 )
= (22/7×49×10) + 8
= (22/7× 490 ) + 8
= 1.540 + 8
= 1.548 cm³
v = π × r² × t
1.548 = 22/7 × 7² × t
1.548 = 22/7 × 49 × t
t = 1.548 : 154
t = 10.05 cm
4. v = π × r² × t
= 22/7 × 7² × 20
= 22/7 × 49 × 20
= 3.080 cm³
waktu menghabiskan air = v tabung: debit air
= 3.080 : 7
= 440 menit
= 26.400 detik
5. v = π × r² × t
5.000 = 3,14 × 10² × t
5.000 = 3,14 × 100 × t
5.000 = 314 × t
t = 5.000 : 314
t = 15,92 dm
t = 1,592 m
