Answer:

(b) 100cm^2

Step-by-step explanation:

If a square piece of paper will be rolled to form a cylinder then,

Area of the paper= Curved surface area of the cylinder

So as given in the question,

Side of the sqaure paper= 10cm

So area of the square paper= (side)^2

= (10)^2

= 100cm^2

Hence, Curved surface area of cylinder is 100cm^2
