radius = 7m
height = 5m
sheet required = csa of cylinder + area of both upper and lower base
= 2pie * r * h + 2pie r×r
= 2pie r ( h + pie * r)
= 1188 m^2
height = 5m
sheet required = csa of cylinder + area of both upper and lower base
= 2pie * r * h + 2pie r×r
= 2pie r ( h + pie * r)
= 1188 m^2

diameter of cylinder=14m
its circumference=2×pi×r
=pi×d
=14m×22/7
=44m=breadth of rectangular sheet
height of cylinder=lenght of the rectangular sheet=5m
a rectangular sheet of length5m and bredth of 44m is require to make the cylinder.
