A rectangular sheet of paper, 44 cm× 20 cm, is rolled along its length to form a cylinder. Find the total surface area of the cylinder thus generated.
Given: Length = 44 cm
Breadth = 20 cm
To find: TSA of cylinder.
Circumference of circle = 2πr
TSA of cylinder = 2πr (h + r)
Dimensions of rectangular sheet of paper = 44cm × 20 cm
When this sheet of paper is rolled along its length:
Circumference of base thus form = 44 cm
Radius = 7 cm
Height = 20 cm
∴ Total surface area of cylinder =
