Volume of a cylinder = π r^2 h
volume of cylinder = 1000 cm^3 because 1 litre = 1000 cm^3
volume which is 1000 cm^3 = 3.14 x 7 x 7 x h
1000 cm^3 = 153.86 x h
1000 cm^3 = 153.86h
you divide both sides with 153.86
1000cm^3 / 153.86 = 153.86/153.86h
ans = 6.499 rounded up to one decimal place = 6.5
height = 6.5
