Heya !!!
Length of Rectangular paper = 100 cm
And,
Breadth of Rectangular paper = 44 cm
Circumference of base of cylinder = Breadth of Rectangular paper.
2πR = 44
2 × 22/7 × R = 44
R = 44×7/44
R = 7 cm
Height of cylinder = Breadth of Rectangular paper = 100 cm
Therefore,
Volume of cylinder = πR² H
=> 22/7 × 7 × 7 × 100
=> 2200 × 7
=> 15400 cm³.

Answer:
15400 cm3
Step-by-step explanation:
2πr = 44
r= 7
volume of cylinder= πr^2h
22/7*7*7*100
= 15400 cm ^3..
