We can't take the cylinder so generated as a hollow cylinder as the thickness is negligible.
So, it's better to consider it as a solid cylinder.

Heya !!!
Length of Rectangular paper = 154 cm
And,
Breadth of Rectangular paper = 10 cm
Height of Rectangular paper (H) = 10 cm
Circumference of cylinder = Length of Rectangular paper.
2πR = 154
2 × 22/7 × R = 154
R = 154 × 7/ 44
R = 24.5 cm
Therefore,
Volume of cylinder = πR²H = 22/7 × 24.5 × 24.5 × 10 = 132054/7
=> 18865 cm².
