Question

A hollow cylinder of diameter 14cm and height 10cm is cut along the height and a rectangular sheet is formed. what is the perimeter of the sheet.

Answer 1

so if u will cut along its height
then,
perimeter will be
radius =7 height=10
so perimeter =2(l+b)
2(7+10)
=34cm

Answer 2

Answer:

Perimeter of the sheet is 34 cm.

Step-by-step explanation:

Given

Diameter of the hollow cylinder = 14

radius of the hollow cylinder = 14/2 = 7 cm

height of the hollow cylinder = 10  cm

According to the question the cylinder is cut along the height

so perimeter =2(l+b)

2 * ( 7 + 10 )

=34 cm

Hence, Perimeter of the sheet is 34 cm.
