Answer 1

$\huge\boxed {Answer}}}$

Height of cylinder = 1m = 100 cm

Volume of cylinder = 15.4 liters

= 15400 cm^3 

=> pi *r^2 *h = 15400

=> 22*100 * r^2 /7 = 15400

=> r^2 = 15400 * 7 / 2200

=> r ^2 = 7 * 7

=> Radius of cylinder = 7 cm

Since it is a tank , So it's upper part is opened 

Metal sheet Required to make the tank = CSA of cylinder + Area of base

=> 2*pi *r*h + pi *r ^2 

=> 2 * 22 *7 * 100 / 7 + 22*7 * 7/7 

=> 4400 + 154

=> 4554 cm^2
