Heya Friend,
The dimensions of rectangle is 30cm × 18cm
When rectangle is rolled along its length....
then the perimeter of the base of the cylinder is its breadth and height is length
2πr = 18
r = 9/π
so volume = π × 9/π × 9/π × 30
= 2430/π
When rectangle is rolled along its breadth....
then the perimeter of the base of the cylinder is its length and height is breadth
2πr = 30
r = 15/π
volume = π × 15/π × 15/π × 18
= 4050/π
Ratio = 2430 / π ÷ 4050 / π
= 2430 / 4050
= 3/5 = 3 : 5
Hope it helps
