Question

a square sheet of paper of side 22 cm is rolled to form a cylinder . find the radius of the cylinder ​

Answer 1

Answer:

3.5 cm

Step-by-step explanation:

length of aside of square=perimeter of circle

=2×22/7×r= 22

=3.5 cm radius

Answer 2

The radius of the cylinder is found to be 3.5cm.

Step-by-step explanation:

Given:

Side of the paper= 22cm

On rolling the sheet of paper, the side of the sheet becomes height and the surface becomes its circumference. Therefore,

Circumference found of the base= 22cm= 2πr

2πr= 22

πr= 22/2=11

r= 11x 7/22= 3.5cm

Result:

Thus, the radius of the cylinder is found to be 3.5cm
