Question

PLEASE ANSWER THE RED INK QUESTION ​

Answer 1

Answer:

hey mate your answer is..

Step-by-step explanation:

height of vessel =1m

1m=100cm

therefore 1m=1li

15.4*100=1540cm^2.........

hope it's helps...

Answer 2

Answer:

h = 1 m,

volume = 15.4 litres = 15.4/ 1000 m3 = 0.0154 m3

Also, volume of the cylinderical vessel = π r2h

⇒ 0.0154 = 22/ 7 × r2 × 1

⇒ r2 = 0.0154 × 7/ 22 = 0.0049

⇒ r = 0.07 m

∴ Total surface area of the cylinder = 2πr (h + r)

= 2 × 22/ 7 × 0.07 (1 + 0.07) m2

= 44 × 0.01 × 1.07 m2

= 0.4708 m2

Hence, 0.4708 m2 of metal sheet would be needed
