A closed cylindrical tank of radius $7 m$ and height $3 m$ is made from a sheet of metal. How much sheet of metal is required?

Given, radius $r = 7$ m and height $h = 3$ m

Total surface area $= 2 π r (r + h)$
$= 2 π \times 7 (7 + 3)$
$= 2 π (7) (10)$
$= 440 m^{2}$

Sheet of metal required $\Rightarrow 440 m^{2}$

A closed cylindrical tank of radius 7m and height 3 m is made from a sheet of metal. How much sheet of metal is required?

Given, radius r=7 m and height h=3 m Total surface area =2πr(r+h)=2π×7(7+3)=2π(7)(10)=440 m2Sheet of metal required⇒440 m2
