Answer:
Step-by-step explanation:
Here is your answer.
Length is 30 cm
Breadth is 18 cm
I case
If it's fold along length than
Length is Circumference = 30 cm Hence
2πr = 30
Height is 18 cm
Volume is = πr^2h
= π(15/π)^2×18
II CASE
When it's fold along breadth then
Breadth is Circumference = 18 cm
2πr = 18
Height is 30 cm
Volume = πr^2h
= π(9/π)^2 ×30
Now Ratio of their Volume is
Therefore Ratio is 5 : 3
If case I Ratio is 3 : 5
