SOLUTION:-
Given:
A closed cylindrical tank of height 1.4m & radius of the base is 56cm.
Therefore,
Radius, r= 56cm
In metre 0.56m.
&
Height= 1.4m
So,
The metal sheet required, we need the total surface area of the cylinder.
Total surface area of the cylinder;
=) 2πr(r+h)
=) 2× π ×0.56(0.56 +1.4)
=) 2× 22/7 × 0.56 (0.56 +1.4)
=) 2× 22 × 0.08× 1.96
=) 6.89
=) 6.9m²
Hope it helps ☺️
