Step-by-step explanation:

It is given in the question that,

Diameter of the cylindrical tank = 14 m

Radius of the cylindrical tank =  14/2

= 7 m

Height of the cylindrical tank = 5 m

Now,

In order to find the total area of the metal sheet required we need to find the total surface area of the tank.

Hence,

Total surface area of the cylindrical tank =  2πr (r+h)

= 2 ×  22/7 × 7 (7+5)

=  44 × 12

= 528 sq m

Hope it helps you.

Answer:

diameter=14m

so, radius=14/2=7m

height=5m

metal sheet will be required=total surface area of cylinder

=2πr(h+r)

=2×22/7×7(5+7)m^2

=44(12)

=528m^2(answer)
