Question

a rectangular sheet of paper of dimensions 44 cm*18 cm is rolled along its length and a cylinder is formed. find the volume of the cylinder formed

Answer 1

as rectangular sheet is rolled along it's length  circumference of the base circle of cylinder is
                         2 x 22/7 x r=44
                                   r=7

now volume of cylinder= 22/7 x r square x h
                                    = 22/7 x 7 x 7 x 18
                                     =2772 cm cu.

Answer 2

Answer:

Step-by-step explanation:

The sheat was turned around to meet up a cylinder so now the circumference of the circle is the breath of the rectangle so it must be 14

Now the length of the cylinder is its height so it is 22

Now the formula of of surface area of the cylinder will be 2 pi r h is equal to 14 so after the radius will come out as 12 upon 121 now put this value in the formula pi r squared h to take out the volume
