radius of cylinder = 56 cm = 56/100m = 0.56m
height of cylinder = 1.4 m
total metal sheet required to make cylinder
= total surface area of cylinder
= 2πr(r+h)
= 2*3.14*0.56(0.56 + 1.4)
= 3.5168*1.96
= 6.89 m²
height of cylinder = 1.4 m
total metal sheet required to make cylinder
= total surface area of cylinder
= 2πr(r+h)
= 2*3.14*0.56(0.56 + 1.4)
= 3.5168*1.96
= 6.89 m²
