Question

the lateral surface area of a hollow cylinder is 4224 cm ^2 it is cut along its height and formed a rectangular sheet of width 33 cm find the perimeter of rectangular sheet

Answer 1

Given that lateral surface area of a hollow cylinder is 4224 cm²

 We know that Area of rectangle= Area of the hollow cylinder

Let the length of the rectangle be l

Area of rect= l * b
⇒ 4224= l * 33
⇒ l= 4224/33
⇒ l= 128 cm

Perimeter of the rectangular sheet= 2( l +b)
                                                      = 2 (128 + 33)
                                                      = 2 ( 161)
                                                      = 322 cm
