Solution

The correct option is A

39.809 cm3


When a rectangle is rolled across the length, then the height of cylinder formed will be same as the width of the rectangle, i.e., 5 cm and the length of the rectangle will be the circumference of the circular base of the cylinder.
2πr=10

r = 5π
Volume of cylinder =πr2h
=3.14×253.142×5
=39.809 cm3
