height of the cylinder =1m
capacity of the cylinder=volume of the cylinder=15.4 litres
=15400 cubic cm
=0.0154 m sq.
so,r2h=0.0154 m sq.
22/7*r2*1=0.0154
r2=0.0154*7/22
r2=0.0049
r=0.07
so the total surface area =2rh+2r2
=2r(r+h)
=2*22/7*0.07(0.07+1)
=0.44*1.07
=0.4708 m sq.

cylinder
Height =1 m = 100 cm
Volume =15.4 l = 15400 cm²
On solving r = 7 cm
Area of sheet req. = 2πr (h+r)
= 2*22/7*7 *( 100+7 )
= 44* 107
= 4708 cm²
