Question

A rectangular sheet of dimension 33 CM *18 cm * is rolled along its breadth to from a cylinder. Find the radius of the cylinder.

Answer 1

Answer:

the rectangular paper has been rolled along its breadth

therefore, it forms the curved surface of cylinder with base circumference as much as 18cm

we have,

$2\pi r \: \\ = 18 \\ r = 18 \times 7 \div 2 \times 22 \\ = 2.86$
