Answer:
Step-by-step explanation:
it is given that the hollow cylinder is converted into a rectangular sheet.
so the b=32cm
Area of cylinder is the same
so, the curved hollow area of the cylinder = area of the rectangle
The curved area of the hollow cylinder=4224cm
Area of the rectangle= l x b
4224= l x 32
l= 4224 divided by 32
l= 132 cm..
then we have to find its its perimeter
perimeter of a rectangle= 2(l+b)
= 2(132+32)
=2(164)
= 328 cm...... that is practically the answer my friend..... :)
