2. Volume = phi x r x r x t
2.156 cm^3 = 22/7 x r^2 x 14
2.156 cm^3 = 44 x r^2
r^2 = 2.156 cm^3 : 44 cm^2
r^2 = 49
r = V49
= 7 cm
Diameter = 2 x r
= 2 x 7 cm
= 14 cm
Keliling Alas Tabung = phi x d
= 22/7 x 14 cm
= 44 cm

3. volume = 1/4 x phi x d x d x t
693 cm^3 = 1/4 x 22/7 x 7 cm x 7 cm x t
693 cm^3 = 77/4 x t
t = 693 cm^3 : 77/4 cm^2
t = 693 cm^3 x 4/77 cm^2
t = 36 cm

4. volume Susu = 4 x phi x r x r x t
= 4 x 3,14 x 4 cm x 4 cm x 9 cm
= 1.808,64 cm^^3
Jadi volume susu yang dibeli Ibu Leni adalah 1.808,64 cm^3

5. volume = 1/4 x phi x d x d x t
= 1/4 x 3,14 x 50 cm x 50 cm x 120 cm
= 235.500 cm^3
= 235,5 liter
Jadi volume minyak di dalam drum adalah 235,5 liter
