Question

pls answer with process

Answer 1

Given LSA of a hollow cylinder = 2112cm^3.

Given the width of the sheet = 33cm.

Let the length of the sheet be x.

We know that Area of rectangle = l * b

2112 = x * 33

x = 2112/33

x = 64cm.

Therefore the length of the rectangular sheet = 64cm.

Now,

We know that perimeter of the rectangular sheet = 2(l + b)

                                                                                   = 2(64 + 33)

                                                                                   = 194cm.


Therefore the perimeter of the rectangular sheet = 194cm.


Hope this helps!
