Answer:
To Find :
Metal sheet is required.
Formula to be used :
Total metal sheet required = Total Surface Area of the cylinder.
That is 2πr(r+h).
Solution :
Putting all the values, we get
Total metal sheet required = Total Surface
Area of the cylinder.
Total metal sheet required = 2πr(r+h)
Total metal sheet required = 2 × 22/7 × 0.56(0.56 +1.4)
Total metal sheet required = 2 x 22 x 0.08 × 1.96
Total metal sheet required = 6.8992 m²
Hence, 6.8992 m² Metal sheet is required.
