Question

The lateral surface area of a cylinder metal pipe is 5,635 cm². When it is cut along the height of the pipe, we get a rectangular sheet of width 33 cm. Find the perimeter of the rectangular sheet.​

Answer 1

Answer :

The perimeter of the rectangular sheet is 407.5 cm.

Step-by-step explanation :

To Find,

• The perimeter of the rectangular sheet

Solution,

Given that,

• Lateral surface area = 5635 cm²
• The width of the sheet = 33 cm

Therefore,

Curved surface area of a hollow cylinder = Area of rectangular sheet.

» 5635 = lenght × breadth

» 5635 = lenght × 33

» lenght = 5635 / 33

» lenght = 170.75

Hence, lenght of the rectangle is 170.75 cm

Therefore, the perimeter of the rectangle is

We know that,

Perimeter of rectangle = 2 ( Length + Breadth )

» 2 ( 170.75 + 33 )

» 2 × 203.75

» 407.5 cm

Hence, the perimeter of the rectangle is 407.5 cm
