Step-by-step explanation:

Length of rectangular sheet = Height of

cylindrical sheet h So, Height of cylindrical sheet =44cm

According to question=>

Area of rectangular sheet = Lateral surface area of cylindrical sheet

So, I*b = 2*pi*r*h 44 *222* 3.14 * r* 44 968 276.32* r r = 3.50

r = 968/276.32

So, T. S. A. of cylindrical sheet = 2*pi*r(r+h)

=2*3.14*3.50(3.50+44)

= 21.98*47.5

= 1044.05 cm^2.
