Solution and Explanation
A hollow cylinder is cut along its height to form a rectangular sheet.
Area of cylinder = Area of rectangular sheet
4224 cm2 = 33 cm × Length
Length =\(\frac{4224\ cm^2}{33\ cm}\)
=128 cm
Thus, the length of the rectangular sheet is 128 cm.
Perimeter of the rectangular sheet = 2 (Length + Width)
= [2 (128 + 33)] cm
= (2 \(×\) 161) cm
= 322 cm
