(¡)Height of cylinder=27720×7/(22×21^2)=20cm
Step-by-step explanation:
(¡)First convert litres in to cm^3 take it as the volume of the cylindrical container
(¡¡)Then use V=22/7×r^2×h equation and substitute the values to V and r. Then find the value of h
#V=27.72×1000 (V= volume)
# r = 42/2=21 (r = radius)

Answer:
79 ft
Step-by-step explanation:
