Question

Heya User,

Answer the Question :-

The lateral surface area of a hollow cylinder is 4224 cm². It is cut along its height and formed a rectangular sheet of width 33 cm. find the perimeter of rectangular sheet.

Answer 1

Area of Rectangular Sheet = Surface Area of the Cylinder

Area of Rectangle = l x b

Or, l x b = 4224

l x 33 = 4224

l=4224/33=128

Perimeter = 2(128+33)

P=322cm

Answer 2

LATERAL SURFACE AREA = ARE OF RECTANGLE

4224 = lb

given b = 33

33l = 4224

$\large{ \: l= \: \frac{4224}{33} }$

= 128

Perimeter = 2(l + b)

= 2(33 + 128)

= 2 × 161

$\huge \boxed{= \: 332 \: cm}$

THANKS

HOPE IT HELPS YOU DEAR
