Question

The lateral surface areas of a hollow cylinder is 4224 cmsquare .it is cut along its hight and formed a rectangle sheet of width 33cm . find the perimeter of rectangular sheet

Answer 1

area of cylinder=area of rectangle sheet
so,4224=lb
i.e,4224=l*33
so,l=4224/33=128
so, length of recatngle=128cm
and,breadth of rectangle=33
A/Q,
perimetre of rectangle=2(l+b)
i.e,2(128+33)
i.e,2*161
i.e,322cm
so the perimetre of the recatngle=322cm
