Answer:

7.7 square metres or 7.669 square metres of metal sheet

Step-by-step explanation:

Volume of cylinder = 2×22/7×r×100cm

15.4 litres = 15,400 cm cube

Radius = 15 400×7/22 × 50

= 98cm

Surface area of cylinder = (2×22/7×49^2) + (2×22/7×49 × 100)

= 15 092 + 61 600

= 76 692 square cm

= 7.669 square metres of metal sheet required
