Answer 1

Answer:

a closed cylindrical tank of height 1.4m and radius of the Base is 56cm is made up of a thick metal sheet how much metal sheet is required

Step-by-step explanation:

1. cylindrical tank of height 1.4m.

2. radius and Base 56cm.

3.thick metal sheet is required.

4. 1.4m height , 56cm of radius and Base 65.

Answer 2

A Closed cylinder tank is made up of a thick metal sheet

Given that:-

$\sf \blue {Height = h = 1.4m}$

$\sf \green {Radius = r = 56 \:cm}$

$\sf \pink{L.S.A \: of \: cylinder = 2\pi rh}$

$\implies \sf \purple{ 2 \times \dfrac{22}{7} \times \dfrac{56}{100} \times 1.4}$

$\implies \sf \red { \dfrac{2 \times 22 \times 8 \times 1.4}{100}}$

$\implies \sf \orange{ \dfrac{352 \times 1.4}{100}}$

$\implies \sf \blue{ \dfrac{492.8}{100}}$

$\implies \sf \green{4.928 \: {m}^{2}}$

$\sf \pink{T.S.A = 2\pi r(r + h)}$

$\implies \sf \purple{2 \times \dfrac{22}{7} \times \dfrac{56}{100} (\dfrac{56}{100} + 1.4)}$

$\implies \sf \red{ \dfrac{2 \times 22 \times 8}{100}(0.56 + 1.4)}$

$\implies \sf \orange{ \dfrac{352}{100}(1.96)}$

$\implies \sf \blue{ \dfrac{689.92}{100}}$

$\implies \sf \green{6.8992 \: {m}^{2}}$

Therefore, Required metal sheet = 6.8992 m².
