Answer:
27.72litres=27.72×1000 cm^3
(¡)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:
Answer is q = 2
Step-by-step explanation:
First make the equation with a constant so p=k/q
then substitute q to 6 and p to 23.
Then you have 23=k/6 and to find k multiply both sides to get k=138
next substitute p as 69=138/q then multiply q on both sides to get 69xq=138 and then divide 69 to 138 go get q which is 2
